Guide & full description

Complete guide: Gum set + Allen key

A compact kit with the small parts that ensure the clean operation of a coil tattoo machine: 3 hex keys, 5 elastic bands, 5 needle bar grommets and 5 spring rubbers. The grommets absorb vibrations and keep the needle centered in the tube; the elastic bands keep the needle bar under tension; and the hex keys give you the right tool for the machine's screws. It's useful both for beginners setting up their first coil machine and for experienced artists who constantly need replacement consumables at their workstation.

How to use

  1. Prepare the setup with gloves, on a clean surface, before starting the session.
  2. Mount the needle bar grommet onto the armature bar pin, then attach the needle bar loop over it — the grommet absorbs vibrations and eliminates metal-on-metal contact.
  3. Place the spring rubber in its position on the spring/armature assembly for additional dampening.
  4. Stretch one elastic band (or two, as preferred) around the machine frame and over the needle bar to keep the bar pressed toward the back of the tube and the needle stable at the tip.
  5. Use the appropriately sized hex key to tighten the machine's screws (for example at the tube vise), without overtightening.
  6. Start the machine and check: the needle should run centered, without metallic noise and without lateral play in the tube.
  7. At the end of the session, discard the used grommets and elastic bands, and clean and disinfect the hex keys — as they are reusable tools.

Tips from us

  • Replace the grommets every session or as soon as they become soft, stiff, or cracked — a worn grommet lets the needle wobble sideways, and it shows directly in line quality.
  • Always keep a few spare sets: they are among the cheapest consumables, but running out can stop you in the middle of a session.
  • Don't overdo the number of elastic bands — too many increase friction on the needle bar and strain the mechanism; adjust until you get the tension that stabilizes the needle without braking the stroke.
  • Keep the kit away from heat and direct light — rubber degrades over time even when not used.
  • Keep the hex keys at the workstation, in the clean area, so you don't have to search for tools with gloves on during work.
  • If the machine suddenly becomes noisy or the line "shakes", first check the grommets and elastic bands — most of the time the cause is there, not in the machine.
Warning: Grommets and elastic bands are consumables: do not reuse them from one client to another, even if they appear intact — they may come into contact with ink and fluids, and disinfecting degrades the elastic material. Discard them at the end of each session. The hex keys are reusable but must be cleaned and disinfected after use; if you touch them during work, handle them only with gloves or protect them with a disposable barrier.

Frequently asked questions

What exactly does the kit contain?

The kit contains 3 hex keys, 5 elastic bands, 5 needle bar grommets and 5 spring rubbers. Basically, you get both the dampening and tension consumables for multiple sessions and the tools needed for assembly, all in one package.

What type of machine is this kit used on?

It is designed for coil tattoo machines that work with a needle bar and guide tube — that's where grommets and elastic bands are indispensable. Modern pen-style rotary machines that use cartridges with integrated dampening do not need these parts. If you have a classic rotary with a grip tube and needle bar, check your machine's manual to see if it uses this type of grommet.

What is each part in the kit used for?

The needle bar grommet is mounted on the armature bar pin and connects with the needle bar loop, absorbing vibrations and eliminating metallic noise. The spring rubber provides additional dampening at the spring assembly level. The elastic bands stretch over the machine frame and needle bar to keep the needle pressed and stable in the tube. The hex keys are used to tighten the machine's screws during setup and adjustments.

How often should the grommets and elastic bands be changed?

Ideally every session — they are fast-wearing consumables, and for hygiene reasons they are not reused between clients. Clear signs of wear: the grommet has become soft and no longer centers the needle, has become stiff and no longer dampens, has cracks, or you notice vibration and noise in the tube. Elastic bands lose tension and should be replaced as soon as they no longer hold the bar firmly.

Can I disinfect the grommets and reuse them?

It is not recommended. Besides the risk of cross-contamination, disinfectants degrade the rubber: the grommet becomes soft or brittle and no longer works properly. The cost of a new grommet is insignificant compared to the risk of a compromised line or a hygiene issue — treat them as single-use consumables.

The machine vibrates and makes noise even though I put new grommets. What should I check?

Check step by step: if the needle bar grommet is correctly seated on the pin and the needle bar loop sits well on it; if the elastic band has enough tension to keep the bar pressed toward the tube; and if the machine's screws are tight — use the hex keys from the kit. If the noise persists after these checks, the problem may be with the tube, the needle, or the machine's adjustment, not the grommets.

Product description

Gum set + Allen key The set contains 3 screws, 5 rubber bands, 5 needle rubbers and 5 spring rubbers The Grommets and Allen Key Set is an essential consumable and tool kit for coil tattoo machines, containing dampening O-rings (grommets) together with the hex key needed for installation. Grommets (or nipples) are rubber or silicone rings mounted on the needle bar serving two critical functions simultaneously: dampening vibrations transmitted from the electromagnetic mechanism to the needle, and keeping the needle centered in the grip tube guide. Without functional grommets, the needle vibrates excessively, produces metallic noise in the tube, and moves laterally — all seriously compromising line quality and procedure comfort. Grommets wear quickly in professional use — rubber degrades through contact with ink, disinfectants, and repeated mechanical stress, becoming too soft (no longer centers the needle), too rigid (no longer dampens), or breaks completely. Therefore, they are considered single-use or very short-life consumables, requiring replacement every session or every few sessions. The Allen key included in the set is specifically sized for screws used in tattoo machine component mounting, eliminating the need to search for the right tools. The set offers an excellent quality-price ratio — quality grommets with the necessary installation tool, in a single affordable package. Frequently Asked Questions
