TUBES AND COMPRESSION FITTINGS.
Tubes with inverted nuts and compression fittings are designed for one time assembly. Once
assembled, they must be replaced as a unit if any parts are found defective. Used parts may not seal properly
when used with new ones.
Used tube assemblies in good condition can be installed to their original location without leaking.
Assemble new tubes, compression
sleeves, and inverted nuts as follows:
Slide inverted nut onto end of
Slide compression sleeve onto

other end of tube as required.
Install new tube assemblies as follows:
Insert end of tube as far as it will go into compression fitting to which tube is being installed.
Twist inverted nut into compression fitting and tighten inverted nut against compression
sleeve with open-end wrench (Item 8, Appendix I). Compression sleeve will clamp down around tube and conform
to internal surface of compression fitting and inverted nut.
Repeat previous two steps for other end of tube as required.
