A prelubricated gasket we’ve designed and manufacture right here in northeast Indiana is a simple and reliable seal for joints in concrete pipes, manholes and box culverts.
The unique design of the RFS (Reduced Friction Seal) prelubricated gasket also helps with reducing insertion forces virtually eliminating any twisting of the gaskets or rolling out of the joint.
What is a prelubricated gasket?
The RFS pre-lubricated concrete pipe and manhole gasket is an encapsulated all rubber gasket that is filled with an internal lubricant. This helps save time and money as we’ve eliminated a step in the installation process.
So I don’t have to lube this gasket?
No. The unique design encapsulates the lubricant preventing any collection of debris on the surface that might cause issues during installation.
What specifications does RFS prelube meet for ASTM?
Press-Seal’s engineering and product development team continuously work to ensure that we meet or exceed the most demanding specifications. The RFS meets the following ASTM’s:
- 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
Do you manufacture prelubricated gasket in nitrile?
Absolutely. It is specially developed rubber for applications where exposure to petro by-products or solvent based products might be used. The Nitrile RFS cross-sections are manufactured in a variety of profiles similar to the standard RFS cross-sections and contain the same type of lubricant as the standard RFS.
What precast products can you use prelube for?
Whether you use our standard compound or nitrile, the RFS prelubricated gasket can be used on:
- Concrete manholes
- Wet wells
- Square pump and lift stations
- Stormwater structures
- On-site treatment structures
- Junction chambers
- Grease interceptors
- Concrete pipe
What is the manufacturing process for RFS gaskets?
The process is a standard extrusion using high precision molds and dies for splicing. Press-Seal has been manufacturing gaskets for over 70 years and is the only gasket manufacturer in the precast market who mixes their own rubber. This long standing company history, coupled with our vertical integration provides you with greater quality control and delivery.
