Taper thread sealant for piping
JP30ZDE010102005
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. Assemble the part again according to (1) and
(2).
