ParFab™ Extruded & Spliced Profile


The Parker TechSeal Division JBL Operations produces a wide range of “standard” and “custom” extruded products fabricated from a variety of “Sealing Grade” material formulations. This section contains a listing of standard extruded profiles used to fabricate spliced rings, gaskets or long length bulk footage on a spool or coiled for customer fabrication.

Extruded and Spliced/Fabricated Products are made utilizing a hot vulcanization process to provide spliced rings and custom gaskets from either “standard” or “custom” cross-sectional profiles. TechSeal’s precision extruded and spliced products offer an ideal, cost effective sealing solution for many applications. These include low-closure force seals, large diameter profiles that cannot be molded, or requirements for hollow O-rings, non-standard solid O-rings, and other extruded profiles with an inside diameter larger than 1.500” (38.1mm).” All TechSeal extruded and spliced parts are “Hot Vulcanized,” and provide the designer with a tremendous amount of flexibility and can be attached/assembled into grooves or onto flat surfaces.

Long Length Extrusions are typically supplied on cardboard or plastic spools, or free-coiled in lengths of up to 5000 feet depending upon cross-section.

Extruded Profile Availability

TechSeal offers many standard extruded profiles in Solid & Hollow-O, Solid & Hollow-D, UChannel, Rectangular, Solid & Hollow Square, and Hollow-Dart configurations.
