TECTITE Fitting Assembly for Copper and CPVC Tube
Copper water tube per ASTM B88, Types K, L, & M, both hard drawn and annealed, may be used with
TECTITE fittings. In addition, CPVC water tube per ASTM D2846/2846M-99 may be used with TECTITE
fittings (see page 1 for a list of compatible materials).
Step 1 – Cut the tube with a tube cutter. The cut should be perpendicular to the centerline of the tube.
Step 2 – Remove burrs by chamfering the tube at the inside and outside diameters..
Step 3 – Mark the tube exterior at the depth shown. The tube insertion depth is the same whether the tube
material is Copper, CPVC, or PEX.
Tube Insertion
Size Depth
1/4 15/16"
3/8 15/16"
1/2 15/16”
3/4 1-1/8”
1 1-5/16”
Step 4 – Holding the fitting tightly, insert the tube straight into the fitting with a twisting motion until the depth
mark on the tube outside diameter is aligned with the end of the fitting. If the mark and the end of the fitting
are not aligned, then continue to push the tube to the full insertion depth.
Note - Inserting a properly chamfered tube straight into the TECTITE fitting cup will
produce a leak free joint, reduces insertion force, prevents o-ring damage, and
insures the tube is easily inserted to the correct insertion depth. Inserting the tube
at an angle and pulling it into proper alignment is poor assembly practice and may
result in a leaking joint.
TECTITE Fitting Assembly for PEX Tube
TECTITE fittings are designed to join PEX water tube that meets the requirements of ASTM F876, F877. In
order to make an effective joint, a tube liner is required, see Figure 1. Tube liners have been specifically
designed by EPC for use with the TECTITE fitting product line; do not substitute any other manufacturer’s
tube liner. Liners are available in 1/4” through 1” sizes.
