Uniseal The UNISEAL® replaces the traditional plumbing hardware with a single injection moulded unit requiring no component parts. The Uniseal® is also suitable for pipe to pipe joining and on curved surfaces in PVC, Steel, Aluminum, Copper, etc. It requires no sealants, glue or bolts. The Uniseal® is resistant to greases, oils, acids, heat & cold. Most importantly, no liquid or air leaks under pressure or suction. Installing the Uniseal® is a simple process. Cut a hole in the wall of a tank or other surface, insert the seal, then slide the pipe through using detergent as a lubricant. Suitable for the Building, Plumbing, Agricultural & Marine Industries. The standard Uniseal® sizes are designed to fit PVC & Steel pipes 3/16" to 6" through wall thicknesses of 1/8" to 1/2". The fittings are suitable for use in applications up to 65psi. Installation Instructions Step 1- Using a holesaw, cut a hole to the correct size for the Uniseal® you are installing. Ensuring that the hole is a clean cut as irregularities could result in poor seating and leakage. Ridges and burrs must be removed from holesaw cut. Eg: A 2" Uniseal® = 3" holesaw. Step 2 - Place the Uniseal® into the hole with the wide side facing the direction the pipe is going to be inserted (see diagram). Step 3 - Chamfer/bevel the edge of the pipe to 15° min. Ensure that there are no sharp points to cut the Uniseal® fitting. Step 4- Wet and apply liquid detergent to the end of pipe to be inserted into the tank. Then drive the pipe through the Uniseal® from it's wide side. (It may be necessary to use a mallet & dolly). The detergent will be squeezed off as the pipe passes through the Uniseal®. The coefficient of friction of the rubber holds the pipe tightly in place. DO NOT use silicone, grease or Vaseline, as anything with a slippery or greasy base will cause the marriage between the pipe and the Sarlink® in the Uniseal!® to fail under pressure.
