Fabric Reinforced Seals Overview
Fabric Reinforced Seals (FRS) were introduced by Johns Manville in the early 1980s, and are widely known as JM Clipper® Seals. These seals found a niche in the oil seal market because of their unique semi-rigid frame and ease of installation in the field. They are used as a viable option to replace metal case oil seals in the field because the proper installation tools for metal case oil seals are not readily available.
Because Fabric Reinforced Seals are not constructed from metal, concerns with rust and corrosion are eliminated. Damage during installation is circumvented and the composite material acts more like a gasket type seal making it effective when the bore is worn. The nonmetallic construction also allows for the seal to be split, if necessary. Split versions of Fabric Reinforced Seals include a hook and eye spring, which can be detached and reattached during installation. Solid versions of Fabric Reinforced Seals have a fully threaded spring, which is removable as a whole if desired.

Fabric Reinforced Seal Part Numbers
Fabric Reinforced Seals feature an integral molded rubber fiber outer case and an elastomeric seal lip. Some profiles are loaded with a stainless steel spring, such as the C Profile (corresponding to JM Clipper® Seal Style: LDS) shown below. We have a unique part numbering system that starts with FRS, Size #, Profile, Material (if not Nitrile), and Durometer (if not 75). The following are examples of the part numbering system used for Fabric Reinforced Seals. The top Fabric Reinforced Seal part number is a C Profile made with 75 Durometer Nitrile. The bottom Fabric Reinforced Seal part number is a C Profile made with 90 Durometer Viton®. Both part numbers are the same size with the Size # corresponding to a Shaft of 3 inches, a Bore of 4 inches, and a Width of 0.625 inches.
Fabric Reinforced Seal part numbers may also be found using the Oil Seal Size Chart. The interactive chart will display matching sizes as dimensional values are input for Shaft, Bore, and Width. The Oil Seal Size # is hyperlinked to our online store, which will display all sizes matching the selection.
Profile & Material Selection
The two tables below show profiles and materials, respectively. In the first table, Fabric Reinforced Seal profiles are displayed with a Global O-Ring Profile, corresponding JM Clipper® Profile(s), Profile Image, and Description. The Global O-Ring Profile always follows the Size # in the Fabric Reinforced Seal part number. In the second table, shows material and corresponding code. If the Fabric Reinforced Seal is not Nitrile, the part number will have the Material immediately following the Global O-Ring Profile.
