Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent
To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.
Straight offset reducers connect one pipe to a smaller-diameter pipe, keeping your pipes aligned for obstruction-free flow in either direction. They are also known as eccentric reducers.
Connectors with a stainless steel sleeve reinforce the connection to increase shear strength.

Low-Pressure Clamp-On Connectors for Chemical Waste

- For Use With: Acetone, Alcohol, Ammonia, Bleach, Calcium Chloride, Chlorine, Citric Acid, Fluoboric Acid, Hydrochloric Acid, Phosphoric Acid, Salt Water, Sodium Carbonate, Sodium Chloride, Sodium Hydroxide, Sulfuric Acid (30%), Water
- Temperature Range: 0° to 180° F
- Specifications Met: ASTM C1173
- For Pipe Material: See table
With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping. The connectors are 316 stainless steel for excellent corrosion resistance. They stand up to wet environments, just like 304 stainless steel, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.
To install, chamfer and deburr both ends of the pipe you need to join. Mark each pipe adjacent to the connector bands and apply 10 layers of the PTFE tape directly over each line. Doing this creates a seal between the sleeve and the pipe for extra leak protection. Then, center the FEP sleeve over the tape and use a heat gun to shrink the sleeve onto the pipe. Next, center the connector and tighten the clamps to 60 inch-lbs. to form a tight seal. Finally, test for leaks.
