EPES CNC Duralumin H+PTFE Double O-Ring Nozzle 21.9mm

The EPES CNC Duralumin H+PTFE Double O-Ring Nozzle is a precision-engineered replacement nozzle designed to elevate your gearbox performance through superior build quality and air seal efficiency.

Key Features

• CNC-machined duralumin construction – lightweight yet rigid, resisting wear and deformation
• Double O-ring design – dual sealing surfaces for maximum air-tightness and FPS stability
• H+PTFE coating – low-friction material reduces wear on cylinder head and improves longevity
• Precise 21.9mm bore – direct fitment to compatible gearboxes without modification
• Drop-in upgrade – no shimming or fitting required on most V2/V3 platforms

Real-World Use Cases

This nozzle is ideal for skirmishers and competitive players seeking reliability and consistency. Upgrading from a worn or standard plastic nozzle will noticeably tighten your air seal, reduce FPS variation between shots, and extend gearbox life. Milsim players will appreciate the durability for prolonged skirmish sessions.

Technical Specifications

• Material: Duralumin (CNC-machined) with H+PTFE coating
• Bore diameter: 21.9mm
• O-ring configuration: Dual O-ring (increased seal area)
• Compatibility: V2/V3 gearbox platforms (verify fitment with your build)
• Weight: Minimal impact on gearbox balance

Compatibility & Upgrades

This 21.9mm nozzle fits most standard V2 and V3 AEG gearboxes. Before ordering, confirm your current gearbox type and nozzle bore size. It pairs well with upgraded springs, air-seal hopup units, and reinforced cylinder heads for a complete gearbox refresh. Check your specific platform’s fitment; some rare builds may require minor adjustment.

UK Legal & Site Notes

This is a standard internal upgrade component with no legal restrictions in the UK. Site chronograph requirements remain unchanged; a tighter air seal may slightly increase FPS on the same spring, so test before your next game.
