The Complete Magnum Gen 2 Cartridges Compatibility Guide

July 17, 2026 - 2 weeks ago

Choosing the right tattoo cartridge is only part of the equation. Equally important is ensuring your cartridges are compatible with your tattoo machine and grip. Even the highest-quality cartridges cannot perform as intended if they do not fit securely or operate correctly with your equipment. Fortunately, Magnum Gen 2 Tattoo Cartridges are designed around the industry-standard universal cartridge connection, making them compatible with the vast majority of professional rotary tattoo machines and cartridge grips on the market.

This guide explains everything you need to know about Magnum Gen 2 cartridge compatibility, including which machines they work with, how universal cartridge systems function, what to look for when choosing compatible equipment, and how to achieve the best performance from your setup.

Are Magnum Gen 2 Cartridges Universal?

Yes. Every Magnum Gen 2 Tattoo Cartridge features a universal cartridge connection, allowing it to fit most professional rotary tattoo machines and grips that accept universal-style cartridges. The cartridge securely locks into the machine using a standard twist-and-lock mechanism, providing a stable connection while allowing the needle to move freely during operation.

This universal fitting has become the industry standard for professional cartridge systems, giving artists the flexibility to use their preferred machine without being restricted to one cartridge brand.

What Is a Universal Cartridge Connection?

Universal cartridge connections were developed to standardise cartridge compatibility across different manufacturers. Instead of proprietary fittings that only work with specific machines, a universal connection allows artists to use compatible cartridges across a wide range of professional rotary pens and cartridge grips. The system consists of a standardised cartridge body, a locating groove, a twist-lock fitting, and a rear drive bar engaged by the machine's cam or drive mechanism.

Once inserted and rotated into position, the cartridge remains securely seated while the machine drives the needle with consistent, controlled movement. This design also allows cartridges to be changed quickly during a tattoo without replacing the grip or machine.

Which Machines Are Magnum Gen 2 Cartridges Compatible With?

Because Magnum Gen 2 uses the universal cartridge standard, the cartridges are compatible with most professional rotary pen-style machines that accept universal cartridges. Examples include:

• Dragonhawk Fold 2 Pro

• AVA EP7+

• Bishop Power Wand

• FK Irons rotary pen machines with universal cartridge compatibility

• Many other professional rotary pens using the standard cartridge fitting

As long as your machine is designed to accept universal tattoo cartridges, Magnum Gen 2 cartridges should fit securely.

Machines Available from Magnum Tattoo Supplies

If you're building a complete setup, Magnum Gen 2 cartridges pair perfectly with professional rotary machines available from Magnum Tattoo Supplies. All three machines below feature a universal cartridge connection, making them fully compatible with the complete Magnum Gen 2 cartridge range.

Whether you're using a Dragonhawk Fold 2 Pro, AVA EP7+, or the Bishop Power Wand, Magnum Gen 2 cartridges fit securely using the industry-standard universal cartridge connection, allowing you to switch quickly between cartridge configurations without changing your machine.

Which Magnum Gen 2 Cartridges Are Compatible?

Every configuration within the Magnum Gen 2 range uses exactly the same universal cartridge fitting. That means compatibility remains identical regardless of which cartridge type you choose.

Whether you're switching from a fine liner to a large magnum during a session or changing between different needle sizes, the fitting remains exactly the same.

Does Needle Size Affect Compatibility?

No. Needle grouping, diameter and taper have no effect on machine compatibility. For example, 01RL fits exactly the same as 18RL, a 27RM uses the same cartridge connection as a 05RM, and a Whip Shading Magnum locks into the machine in the same way as a Round Shader. The only differences are the internal needle configuration and intended tattooing application.

Does Needle Diameter Affect Compatibility?

Needle diameter changes the way ink flows and how the cartridge performs, but it does not alter compatibility. Across the Magnum Gen 2 range, you'll find:

• 0.20 mm (#06 Extra Bugpin)

• 0.25 mm (#08 Bugpin)

• 0.30 mm (#10 Standard)

• 0.35 mm (#12 Standard)

Regardless of diameter, every cartridge fits the same universal connection.

Does Needle Taper Affect Compatibility?

No. Needle taper only changes the length of the sharpened point on the needle. Magnum Gen 2 cartridges are available with short taper (2.5 mm), medium taper (3.5 mm), long taper (6.5 mm), and extra long taper (8 mm). These specifications influence precision, ink delivery and tattooing style but do not affect how the cartridge fits your machine.

Built for Reliable Performance

Compatibility is about more than simply fitting into a machine. A cartridge should also remain stable during use and deliver consistent performance throughout the tattoo. Every Magnum Gen 2 cartridge includes several design features that support reliable operation:

• Triple stabilisation system to minimise needle movement

• Silicone safety membrane to help prevent fluid from travelling back into the machine

• Medical-grade 304 stainless steel needles

• Transparent polycarbonate housing for improved visibility

• Comfort finger ledge for greater control

• Colour-coded housings for faster identification

• EO gas sterilisation

• Individual blister packaging

These features remain consistent across the entire Magnum Gen 2 range.

Why the Silicone Safety Membrane Matters

Every Magnum Gen 2 cartridge incorporates a silicone safety membrane. This membrane creates a barrier between the cartridge and the machine, helping reduce the risk of ink, fluids or contaminants travelling back into the grip or motor. In addition to supporting hygiene, the membrane helps maintain consistent needle tension throughout the tattooing process, contributing to smoother and more predictable needle movement.

Switching Between Cartridges During a Tattoo

One of the greatest advantages of adopting a universal cartridge system is the incredible speed and efficiency with which you can switch between different needle configurations during a single session, all without needing to swap out your machine or grip. An artist can seamlessly transition through every stage of a tattoo using the same hardware setup. 

For instance, you can begin the session by laying down sharp outlines with a Round Liner, and then immediately transition to a Round Shader to handle tighter, detailed shaded areas. Following this, you can quickly swap in a Curved Magnum to execute smooth, realistic black and grey gradients, before finally clicking in a Straight Magnum to pack in larger areas of solid colour fill. 

Because every cartridge in the Magnum Gen 2 range shares the exact same physical fitting, these critical configuration changes can be completed in seconds. This streamlined compatibility keeps your focus entirely on the skin and maintains a highly efficient, uninterrupted workflow from start to finish.

Choosing the Right Machine Stroke

Although cartridge compatibility is universal, machine stroke length should still be matched to the work being performed. As a general guide:

The stroke length is determined by the tattoo machine, not the cartridge itself. Magnum Gen 2 cartridges are designed to operate with compatible rotary machines across a range of stroke lengths, allowing artists to choose the setup that best suits their technique.

Common Compatibility Questions

Many artists new to cartridge systems have similar concerns about compatibility. Here are some of the most common.

Will all Magnum Gen 2 cartridges fit the same machine?

Yes. Every cartridge in the range uses the same universal cartridge connection.

Can I mix different cartridge configurations during a session?

Yes. You can freely switch between Round Liners, Round Shaders, Curved Magnums, Straight Magnums and other Magnum Gen 2 configurations without changing your machine.

Do larger needle groupings require a different machine?

No. Larger groupings use the same connection, although some artists may prefer adjusting their machine settings, such as voltage, to suit the cartridge and technique.

Can I use Magnum Gen 2 cartridges with cartridge grips?

Yes. Any professional grip designed for universal tattoo cartridges should accept Magnum Gen 2 cartridges.

Maintaining Compatibility and Performance

To ensure cartridges continue to perform as intended:

• Always use machines and grips designed for universal cartridges.

• Check that the cartridge is fully seated and locked into place before tattooing.

• Inspect each cartridge before use and only use sterile, unopened cartridges.

• Dispose of cartridges after a single use in accordance with local regulations.

• Keep your machine and grip clean and well-maintained to ensure smooth operation.

Following these steps helps maintain both performance and hygiene throughout every session.

Conclusion

The Magnum Gen 2 range is engineered around the industry-standard universal connection, ensuring seamless compatibility with the vast majority of professional rotary machines and grips. Whether your session demands a Round Liner for intricate linework, a Curved Magnum for smooth realism, or a Straight Magnum for efficient colour packing, every cartridge in the lineup fits the same universal system.

By combining this universal fitment with advanced triple stabilisation, a flexible silicone safety membrane, and an ergonomic comfort finger ledge, Gen 2 cartridges provide a highly consistent, dependable experience across all tattooing techniques. Pairing these cartridges with versatile machines like the Dragonhawk Fold 2 Pro, Bishop Power Wand or AVA EP7+ delivers a reliable, high-performance setup capable of handling everything from delicate details to heavy colour saturation with ease.
