O-ring Kit For Sg A138

Features

• Made For SG-A138 Designed specifically for the AirCraft SG-A138 airbrush.
• O-Ring / Seal Kit Replaces critical sealing points that influence pressure stability and spray control.
• Ideal For Servicing Practical maintenance item for rebuilds and leak troubleshooting.
• Restore Proper Fitment Helps components seat correctly and reduces pressure loss.

Benefits

• Reduce Leaks: Fresh seals help stop hissing air leaks and pressure loss.
• Improve Spray Consistency: Better sealing supports steadier atomisation and smoother paint flow.
• More Predictable Operation: Helps restore stable performance for shading, gradients and general spraying.
• Extend Airbrush Life: Regular seal replacement supports long-term reliability and protects internal components.

Extra Information

• Common signs you need new O-rings: air leakage, bubbling, inconsistent spray, spitting, or fluctuating pressure.
• Cleaning tip: Avoid harsh solvents on rubber seals unless the seals are rated for it—some solvents can swell or degrade O-rings.
• Install carefully: Avoid stretching O-rings too much and ensure each ring sits flat in its groove.
• Light lubrication: A tiny amount of airbrush-safe lubricant can help seals seat properly and last longer.
• Test after fitting: Run clean air first to confirm sealing, then flush with cleaner/water before spraying paint.
