Rubber Extrusion

Standard and custom rubber extrusion profiles are available in continuous lengths and intricate profile shapes here at North Coast Seal. We can meet all of your application needs and seal requirements.

Plastic Extrusion

Plastic extrusion is a manufacturing process that melts down raw plastic and forms it into a continuous profile. The heat generated from the turning screws and heaters along the barrel of the machine cause the material to gradually melt.

Plastic Injection

Plastic injection is perfect for the consecutive production of thousands or even millions of parts. It is a great manufacturing process for the production of thermoplastic or thermosetting materials and achieving the specific geometrics that other processes just can’t properly carry out.

PTFE (Teflon®)

North Coast Seal offers PTFE U-cups with Spring-Energized Seals that are made from PTFE and other polymer alloys that are corrosive resistant. A V-shape cantilever beam spring maintains live compression load and the system pressure keeps it in motion. Available in standard and custom rod and piston and face seal designs to meet all your application requirements.


Whether it’s standard fasteners or metric fasteners, North Coast Seal has the solutions you can depend on. From large quantities to custom orders, we are ready to meet your needs no matter the industry!
