Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent

Tighten the bands on these connectors to form a strong seal on pipe or fittings.

Socket end-to-socket end connectors allow you to connect two socket-end (female) fittings without using a pipe; the connectors attach over the end of the fitting. Pipe end-to-socket end connectors connect a pipe to a socket-end (female) fitting. Pipe end-to-corrugated pipe connectors connect a rigid plastic pipe to a corrugated polyethylene pipe; a groove in the coupling matches the groove in the corrugated pipe. They are great for storm and drainage systems.

Saddle-tap adapters allow you to tap into an existing pipeline. They have wraparound clamps that provide nearly 360° contact with pipe; as the clamps are tightened, pressure is uniformly distributed around the pipe for maximum support. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole and tighten the clamps.

Sanitary Sealing Grommets

Style 1

Style 2

Style 3

Styles 1 and 2

Style 3

Create a sanitary seal on through-wall piping, tubing, and cables in food-, cosmetic-, and pharmaceutical-processing areas. Made of silicone, these grommets have a wide temperature range, resist washdown chemicals and cleaners, and are FDA compliant for direct contact with food. They’re also flexible, so hydraulic pressure surges, pipe expansion, and cord flexing won’t break their seal or damage them. No caulk or sealant is needed to install these grommets because their ridges form a strong seal that keeps out dust, debris, and moisture. The ridges also act as guidelines for trimming the center of these grommets to size; they’re sized to standard tube diameters.

To mount the flanges of these grommets, use their drilled holes. Flanges are 316 stainless steel to resist corrosion from washdowns with harsh cleaners and sanitizers.

Style 1 grommets work on tubing that isn’t installed yet.

Style 2 grommets have a split design to wrap over tubing that’s already in place. For a secure seal, crimp the included metal staples over the seal using pliers.

Style 3 grommets are flat, so they’re best for tight spaces.
