RFS Pipe Gasket

RFS prelubricated pipe gaskets provide simple and reliable sealing of joints in concrete pipe, manholes and other precast concrete products.

Download Literature Box Culvert Literature

The RFS pre-lubricated pipe and manhole gasket is an encapsulated all rubber gasket that is filled with an internal lubricant.

The unique design also helps in reducing insertion forces, virtually eliminating any twisting of the gasket or rolling out of the joint commonly found to occur in O-ring and profile gaskets.

How It Works

  • Gasket is stretched over the spigot with the tube lying flat against the spigot.
  • Spigot and bell are homed with little insertion force due to the internal lubricant.
  • The rolling feature fills the small annular space.

Why It's Better

  • Eliminates any external lubrication on joint or gasket.
  • Installs quicker by eliminating the lubrication step.
  • Easier to use around job sites because dirt and debris does not adhere to the gasket because of internal lubricant.

Where To Use

  • Manholes
  • Wet wells
  • Square pump and lift stations
  • Stormwater structures
  • On-site treatment structures
  • Junction chambers
  • Grease interceptors

Meets or Exceeds

RFS Prelubricated Pipe Gaskets meet or exceed all requirements of the following Specifications and/or Test Methods:

  • ASTM C 1619 (Classes C) – Standard Specification for Elastomeric Seals for Joining Concrete Structures • ASTM C 443 – Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets • CSA A 257.3 – Gaskets for Concrete Pipe

Tip

Do not hang RFS gaskets from hooks or pegs in a vertical position.

  1. A rubber gasket shall be employed in the connection of the sanitary and/or storm pipe, manhole or box culvert to ensure a watertight connection.
  2. The rubber gasket shall be RFS (Reduced Friction Seal) as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal.
  3. The rubber gasket shall be the sole element relied on to assure a flexible watertight seal and meet ASTM C433 Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets and ASTM C1619 Standard Specification for Elastomeric Seals for Joining Concrete Structures Class E.
  4. All gaskets shall be extruded or molded in such a manner that any cross-section will be dense, homogeneous, and free of porosity, blisters, pitting, or other imperfections. The gaskets shall be fabricated from an elastomeric material meeting the appropriate classification physical property requirements in section The base polymer shall be natural rubber, synthetic rubber, or a blend of both and be 100% first run material with no recycled content.
  5. Selection of the proper size rubber gasket for the pipe joint requirement, and installation thereof, shall be in strict conformance with the recommendations of the gasket manufacturer. Any testing shall also be conducted in strict conformance with the requirements of the gasket manufacturer.
  1. Stretch RFS Gasket onto spigot of pipe, making sure that mantle is laying smoothly toward end and that gasket body is firmly against shoulder of spigot.
  2. Center pipe spigot and bell, and evenly and smoothly press spigot into bell. Gasket mantle will help center the pipe joint as the mantle moves into clearance space.
  3. Complete assembly until pipe joint is home. Mantle moves into recess behind gasket, cushioning the joint while allowing joint to deflect. Complete installation by following pipe manufacturer’s recommended bedding
    and backfilling practices.
