RFS Pipe Gasket

The RFS concrete pipe gasket meets or exceeds:

  • ASTM C1619: Standard Specification for Elastomeric Seals for Joining Concrete Structures
  • ASTM C443: Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets
  • CSA A257.3: Gaskets for Concrete Pipe

RFS prelubricated pipe gaskets provide simple and reliable sealing of joints in concrete pipe, manholes and other precast concrete products. The RFS gasket is commonly referred to as a “pre-lubed” gasket in the industry. The advantage of an RFS gasket is that the contractor does not have to apply lubricant to the pipe and gasket in order to home them.  RFS pre-lubricated pipe gaskets are now available in the most popular sizes and styles to meet almost any need.

RFS are available in Nitrile-NBR rubber compounds, too. RFS meets or exceeds all the requirements of ASTM C1619 Class C ( Class D for oil resistance), ASTM C443, and CAS A257.3.

Features and Benefits

  • Installs easily and neatly on the pipe spigot
  • Reduces dependency on manpower to properly prepare joint for assembly
  • Requires no external lubrication
  • Installs faster and easier, so less time in the ditch
  • Requires no external lubricant, so pipe joint stays cleaner during handling and assembly

How It Works
RFS Prelubricated Pipe Gaskets have superior materials and technology.

  • Specially developed synthetic rubber is continuously tested and lab-certified for concrete pipe joints conforming to ASTM C-443.
  • RFS is easy to apply to the spigot of the pipe and requires no equalization.
  • RFS helps center the pipe during assembly and this reduces joint homing forces.
  • The mantle of the RFS Gasket fits into the concrete annular space, limiting differential settlement.
  • Special viscosity silicone lubricant to reduce joint homing forces.
