PART NAME FUNCTIONS MATERIALS
1 JAW HOLDER Guiding a tube/pipe to insert properly into EZ-Joint and to be held tight by JAWs. Also, uninstalling EZ-Joint on pushing-in Technyl®2412 GH
2 SNAP RING Functioning as a threshold to prevent parts from disassembly and to support tensile power SUS 304
3 JAW Biting the surface of a pipe/tube to hold and to increase tensile power. The more water pressure pushes the spring backward, the more tensile power JAW generates. SUS 420J2
4 SPRING Helping JAWs to move up and down on pushing the JAW HOLDER back and forth on installing/uninstalling SUS 304
5 SPRING GUIDE Guiding and supporting the SPRING balanced Technyl®2412 GH
6 O-RING 2 Preventing water leakage supporting O-RING 1 EPDM Rubber
7 BACKUP RING Separating O-RING 1 & 2 to prevent from adhesion Technyl®2412 GH
8 O-RING 1 Preventing water leakage
EPDM Rubber
9 Body Body to assemble all the parts SUS 304
