The Professional Standard for 8mm Pneumatic Lines

Standardize your workshop with the RTC 022-H "Aro" profile plug. This 8mm (5/16") Hose Tail fitting is specifically engineered for a secure, direct-to-hose connection. By using a hose barb instead of threaded adapters, you reduce potential leak points and create a more ergonomic, lightweight setup for your handheld pneumatic tools.

Technical Specifications

Why Choose RTC Hardened Plugs?

• Hardened Steel Durability: Unlike soft brass fittings, RTC hardened steel won't "mushroom" or wear down where it locks into the coupler, preventing accidental disconnections.
• Optimized Flow: Designed to maintain high CFM for general-purpose tools like nailers, blow guns, and small impact wrenches.
• Secure Barb Profile: Features precision-machined "bites" that hold the hose firmly, even under high pressure.
• Universal NZ Fitment: 100% compatible with all standard Aro 210 series quick-connect couplers used across New Zealand.

Expert Maintenance Tip

For a leak-free and safe connection, we recommend securing this 8mm hose tail with an Oetiker ear clamp or a high-quality stainless steel worm-drive clamp. Always ensure the hose is pushed fully past the final barb before tightening.
