Taper thread sealant for piping
JP30002010102006
The taper thread of the air pipe joint has application of sealant
[Loctite # 575 (by Japan Loctite)]. Follow the procedures below for
connection or disconnection of pipes.
1. For disconnection
(1) The sealant ( # Loctite 575) has strong sealing feature.
The return torque of the taper joint is increased about 1.5
times the initial tightening torque. When the joint is
disconnected, use a long wrench for disconnection
(2) When a joint at a poorly accessible area is replaced,
remove accessories first and disconnect the joint.
2. For connection
(1) For application of sealant ( # Loctite 575), wipe the
sealing area completely with a rag or thinner. Apply
sealant directly to about three ridges for quarter round
with offset of one ridge from the end. Tighten it according
to the tightening torque in the table below.
Remove dirt completely from the mating part (female)
before tightening.
!CAUTION
•If your eye or skin comes in contact with
sealant, wash it off immediately with water.
Tightening torque of taper joint Unit : N⋅m{kgf⋅cm, lbf-ft}
(2) When a sealing tape is replaced with sealant, remove the
tape completely first as in (1).
!CAUTION
•Be careful to prevent entry of dirt or foreign
matter in the pipe.
(3) If air leak is found after assembly with application of
sealant, air leak cannot be stopped with additional
tightening. Assemble the part again according to (1) and
