Ⅲ. Structure Features
The test cap mainly consists of a body, a nut, a plug, a circlip and an O-ring. The body is a joint capable
of withstanding high pressure. The joint is provided with an O-ring and an external union female joint.
Union nut is made of alloy steel with wrench hole, and can be screwed with hook wrench during installation.
Ⅳ. Use method
1. Align The test cap with the internal coupling head and screw on the union nut. Remove the plug and
connect the pressure line.
2. Use a hook wrench to tighten the union nut to start the pressure test.
Ⅳ.Maintenance
Thread and O-ring shall be coated with lubricating grease and stored with thread protector. If any damage
is found to the O-ring, it shall be replaced in time.
