PVC/PVCO Pipe Gaskets

Drawing on decades of experience, Hamilton Kent develops rubber gaskets for the plastic pipe industry that optimize the performance of the pipe joint while minimizing the amount of rubber required. We can produce premium gasket configurations for virtually any sewer or water pipe joint, including special requirements such as UV or chemical resistance.

  • Single and dual durometer gaskets
  • Broad selection of gasket configurations

Hamilton Kent has been designing and producing gaskets for the plastic pipe industry for decades to ensure watertight or silt-tight pipe for use in water, sanitary, industrial, storm drain, mining and culvert applications.

Typically, PVC/PVCO gaskets are fitted into the bell of the pipe and require a special design and fabrication in order to secure them in place until the pipe is installed at the jobsite. It is critical for these joints to be watertight as the pipes often transport either drinking water or sanitary sewer water. In all cases, the gaskets must perform equally as well as the pipe. For years, Hamilton Kent has worked with PVC pipe manufacturers to deliver an effective solution that consistently performs across these applications, and many others.

Materials and Identification

Plastic pipe gaskets are manufactured from a variety of synthetic rubber compounds. PVC and PVCO gaskets are designed to meet the material requirements of ASTM F477; ASTM D3212; and CSA B137.3.

The applicable specification(s) and intended use for a particular gasket are identified by a colored stripe around the periphery of the gasket:

  • EPDM – Stripe color by manufacturer’s request (typically White/Green)
  • Oil-Resistant – Orange Stripe*

* Note that the additional physical properties required to achieve oil resistance have a significant impact on availability, handling and cost. Please refer to the Oil Resistant Gaskets document under Tech Notes in the Resources section of this website.

The above listing covers the standard North American specifications. Gasket materials are available to meet many other specifications.

Pressure Rating

Our PVC gaskets meet the hydrostatic pressure requirements of specifications of AWWA C900. Our PVCO gaskets meet the hydrostatic pressure requirements of specifications of AWWA C908.

Higher head pressures have been obtained with certain joint designs. Please consult your local Hamilton Kent Representative for gasket selection to meet your specific requirements.
