The OATEY COMPANY 33876 is a 1-inch polypropylene suspension clamp designed to hang and support pipe runs in residential and light commercial plumbing systems. Each clamp is molded from durable polypropylene, a material that resists corrosion and eliminates direct metal-to-pipe contact. The ribbed clamp body holds pipe away from framing surfaces, which reduces the transmission of water line noise through the structure. The open ribbed design also promotes airflow around the pipe, allowing it to cool faster and expand or contract freely during thermal cycling. This pack includes 6 clamps, supplied in a polybag for easy jobsite storage. Licensed plumbers and pipefitters are the primary installers of this product.
These suspension clamps are suited for securing plastic pipe runs in walls, floors, ceilings, and mechanical rooms. The polypropylene construction makes them a practical choice in environments where moisture, condensation, or chemical exposure would corrode metal hangers. The noise-dampening benefit is especially useful in residential builds where water hammer or flow noise is a concern along supply lines routed through living spaces.
Designed as an OEM-style suspension hanger for 1-inch diameter plastic pipe runs in residential and light commercial plumbing applications.
Installation is typically performed by a licensed plumber following applicable IPC or local plumbing code requirements for pipe support spacing. Shut off the water supply before repositioning or modifying any pipe run. Secure each clamp to a structural framing member using a fastener appropriate for the substrate. Do not overtighten fasteners, as this may distort the clamp body and restrict the free expansion and contraction of the pipe.
