LARGE DIAMETER TECTITE FITTINGS
Large Diameter TECTITE Installation and Specifications Manual
TECTITE fittings are a heat free method for joining Copper, CPVC and PEX tube. TECTITE provides a clean
and easy joining method designed to save time and money on installations. Installing a joint with TECTITE is
simple, requiring no extra materials beyond the TECTITE fitting for Copper, CPVC and PEX tubing
installations. The use of solder, flux, and heat, or special pressing tools is eliminated. This lowers costs,
reduces labor time, and allows a clean and efficient installation process. TECTITE is a re-moveable and reuseable fitting system that provides the ultimate flexibility in plumbing system assembly.
Warranty
TECTITE fittings carry a 50-year warranty against manufacturing defects. Contact an EPC representative for
details. All warranties are subject to following good installation practices as outlined in this installation
manual.
Materials and Material Compatibility
TECTITE fittings are designed and manufactured to strict specifications and quality systems. Large diameter
TECTITE fittings are manufactured from Copper or Copper Alloys and utilize EPDM o-ring seals, Nylon and
Zytel plastic components, and a 316 Stainless Steel retaining ring. An ANSI/NSF 61 listed silicone grease is
used to lubricate TECTITE fittings.
Large diameter TECTITE fittings are designed for use with ASTM B88 hard drawn and annealed Copper tube,
Type K, L, or M, in the 1 1/4” through 2” size range, CPVC water tube per ASTM D2846/2846M-99 and PEX
water tube that meets the requirements of ASTM F876, F877.
All TECTITE fittings are designed to operate at temperatures from 0° to 250° F at a maximum working
pressure of 200 psi, with various liquids, and gasses.
TECTITE fittings must not come into contact with household cleaning products, paints, greases, flux, mineral
oils, adhesives, ammonia, nitrates, or other solvent base materials that may be used during or after
installation.
The exterior surface of TECTITE fittings should not be painted.
The use of proprietary chemicals to flush pipes during plumbing system startup should be reviewed with an
EPC representative.
Installation
The TECTITE joining system is designed with easy installation in mind. Basic joining and removal procedures
are identical for every type and size of TECTITE fitting. The following instructions address the assembly
procedures.

TECTITE Fitting Assembly for Copper, CPVC Tube
Step 1 – Cut the tube with a tube cutter or fine tooth saw. 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 ¼ 2-1/4”
1 ½ 2-7/16”
2 2-3/4”
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 ¼” through 2” sizes.
