JieKeLong's press-fit valves are designed for tool-free rapid assembly and leak-tight sealing in modular fluid systems. Key applications include drinking water plumbing, HVAC refrigerant lines, compressed air networks, beverage dispensing systems, and laboratory gas distribution. They play an essential role in enabling quick modifications without system drainage and vibration-resistant connections across maintenance-critical installations.
Press-fit valves enable tool-free installation via integrated collets and O-rings that secure pipes with a single push.
They provide vibration-resistant leak-proof sealing at standard pressures (≤25 bar), preventing disconnections in modular fluid networks.
Minimal pressure drop in fully connected systems due to smooth internal bores matching pipe ID.
Glass-fiber reinforced PPSU bodies and EPDM O-rings ensure chemical resistance and 50,000+ cycle durability in HVAC, plumbing, and compressed air systems.
Prepare pipes with square-cut, deburred ends within ±0.1mm diameter tolerance. Clean sealing zones with isopropyl alcohol to remove oils/debris. Inspect O-rings for nicks or deformation and verify collet spring tension.
Insert pipe axially until audible/visual click confirms full engagement. For angled installations, maintain <5° misalignment tolerance. Never lubricate O-rings – apply force only to valve body, not release collars or levers.
Maintain 2x pipe diameter straight entry for collet grip integrity. Incomplete insertion may cause blow-off under pressure; over-forcing risks O-ring extrusion. Test with 10-minute pressure hold at 1.5x working pressure post-installation to verify zero-leak performance.
Inserting the pipe axially with firm pressure compresses the integrated elastomeric O-ring radially against the pipe surface and valve body, forming an immediate pressure-tight seal.
Simultaneously, the stainless-steel collet fingers snap into position behind the pipe groove, mechanically locking against retraction forces.
Sealing effectiveness relies on elastic O-ring recovery, with system pressure enhancing seal integrity by forcing the O-ring tighter against the sealing interfaces while driving collet teeth deeper into the pipe material.
