REFERENCE STANDARD :
Fittings conform to IS 8805
SURFACE FINISH :
All parts of the Fittings are phosphated and oiled.
ASSEMBLY PROCEDURE :
Cut the tube square to correct length. Cutting edge should be deburred with light filling. Threads, taper seat of the coupling and cutting edge of the sealing ring should be cleaned and lubricated before assembly to make easy joints. Make sure that the cutting edge of the sealing ring is located in the coupling body and collar end faces towards the nut.
Ensure that the end of the tube butts firmly against bottom of the taper portion of the body. Before tightening the nut on the body with the sealing ring, ensure that the coupling and tube are properly aligned. “SUPER” couplings should not be used to align the tubes by pulling nor should they be used as tube support.
Tighten the nut on the coupling body fully so that the sealing ring bites the tube properly. Two spanners should be used, one to prevent rotation of the body and the other one to tighten the nut.
“SUPER” brand couplings can be disconnected or reconnected for any number of times without affecting their pressure tightness. In such reconnecting operations, ordinary spanner - tightness is sufficient. |
