⭕ Gaahleri Teflon O-Ring — Paint Cup Seal
Advanced & Ace Series · GHAD‑39 · GHAD‑68 · GHAC‑98D · GHAC‑Swallowtail
✅ Compatible Models
⚠️ Paint cup seal specifically — not the same as body or valve O-rings. Check your model before ordering.
🔍 What Is This?
A Teflon O-ring specifically sized for the paint cup seat — the junction between the cup and the airbrush body. This is where paint leaks most commonly originate. A fresh, correctly-fitted cup O-ring restores a tight seal and eliminates drips, seepage, and pressure loss at the cup base.
OEM replacement — genuine Gaahleri part. Note: this is the cup-specific O-ring. Body, nozzle, and valve O-rings are separate parts.
🧪 Why Teflon Matters Here
🧴 Survives aggressive cleaners
The cup gets the most direct chemical exposure during cleaning. Standard rubber swells or hardens with repeated solvent contact — Teflon doesn't.
🔒 Maintains seal under pressure
Stable dimensions mean it keeps sealing consistently as pressure builds in the cup — no gradual leak developing mid-session as the material deforms.
🔄 Longer service life
Doesn't absorb paint or solvents, so it stays pliable and maintains its profile longer than rubber alternatives between replacements.
🛠️ When You Need This Part
⚠️ Paint leaking at the cup base — seeping around the cup-to-body joint during use
⚠️ Cup feels loose or unstable — wobbles or doesn't sit firm against the body
⚠️ Visible O-ring damage — cracking, flattening, or hardening on inspection
🔄 Routine service — recommended replacement every 3–6 months under heavy use or frequent solvent cleaning

⚠️ Heads Up
Cup seal only — this O-ring is sized specifically for the paint cup seat. It is not interchangeable with the body, nozzle, or valve O-rings on the same airbrush. Using the wrong size O-ring won't seal correctly.
