ASAB Quick Connect Fittings #28 - Quick Connect Coupling | 1/4" x 1/4"M | 5000psi

Part Code: ASAB-F-HPF28

Introducing the ASAB HPF28 Quick Connect Coupling — a tough, job-site-ready coupling designed to give you fast changeovers on high-pressure airless gear while keeping your plumbing simple and properly rated. Built for professional airless systems, this coupling is ideal when you need quick-connect convenience but also want a male threaded end to adapt straight into a gun, whip line, manifold block, extension, or accessory port without stacking extra fittings.

Rated to 5000 PSI, the QC coupling format streamlines setup and pack-down, reduces downtime when swapping components, and helps standardise kits across the crew. The 1/4" F x 1/4" M configuration is perfect for modular setups where you want fewer joins (less joins = less leak points) while still allowing quick disconnect when you need to swap hoses or accessories.

Whether you’re speeding up changeovers, tidying a gun/whip setup, or replacing a worn coupling that’s started to bind or weep, the ASAB HPF28 is a practical upgrade for high-pressure airless work.

Key Benefits

• Rated to 5000 PSI for high-pressure airless applications

• Quick connect coupling design for faster changeovers and modular setups

• 1/4" Female x 1/4" Male configuration for common adaptor and gun/whip applications

• NPT thread for secure, tapered sealing on compatible high-pressure fittings

• Reduces downtime when swapping hoses, guns, whips, extensions, or accessories

• Minimises extra joiners, reducing potential leak points in the line

• Heavy-duty construction for commercial job site use

What’s Included

• ASAB 5000 PSI QC Coupling 1/4" F x 1/4" M (NPT) — ASAB-F-HPF28

Safety Check

• Depressurise fully before fitting changes: Switch to prime/relief, trigger the gun into a waste bucket, and confirm pressure is at zero.

• High-pressure injection hazard: Never check leaks with your hand — use cardboard or a rag and keep clear of pressurised joints.

• Verify quick-connect compatibility: Ensure the coupling matches the correct plug style/profile in your setup (don’t force mismatched quick-connect types).

• Match thread types correctly: Confirm all mating components are 1/4" NPT (do not mix NPT with BSP/NPSM).

• Pressure rating matters: Ensure all connected hoses and fittings are rated to 5000 PSI or higher.

• Inspect threads and sealing faces: Replace damaged components — cracked or cross-threaded fittings can fail under pressure.

• Pressure test gradually after installation: Start at low pressure, check for leaks, then increase slowly to operating pressure.
