EPES O-Ring Seal Kit – Cylinder Head & Piston NBR70

Maintaining a reliable AEG means keeping internal seals in top condition. The EPES O-Ring Seal Kit provides the essential rubber components needed to restore or upgrade piston and cylinder head seals in your gearbox.

Key Features

• NBR70 rubber construction – durable, temperature-resistant seals
• Piston head, cylinder head, and nozzle O-rings included – comprehensive coverage
• Universal compatibility – fits standard AEG gearboxes
• Cost-effective maintenance – extend gearbox lifespan without full rebuild
• Spare kit essentials – stock these for field repairs and preventative care

Real-World Use Cases

Whether you’re a regular skirmisher replacing worn seals after heavy use, a tech rebuilding multiple gearboxes, or a milsim player keeping spares on hand, this seal kit is invaluable. Air leaks from degraded O-rings cause inconsistent FPS and poor air efficiency; fresh seals restore performance immediately.

Technical Specifications

• Material: NBR70 rubber
• Components: Cylinder head, piston, and nozzle O-rings
• Compatibility: Standard AEG gearboxes (V2, V3, etc.)

Compatibility & Upgrades

These seals work with most AEG platforms. If you’re unsure about your gearbox version, check the cylinder arrangement; standard V2 and V3 boxes are most common in modern AEGs. Pair with a cleaning kit and lubricant for best results.

UK Legal & Site Notes

O-ring kits are uncontrolled spare parts with no legal restrictions. They’re permitted at all UK airsoft sites as they’re internal components with no performance-altering function beyond maintenance.

Keep a set in your tech kit and avoid mid-skirmish FPS drops. Order the EPES O-Ring Seal Kit from Airsoftdirect UK today.
