Precision Molded Rubber Parts
Seals for a broad range of applications are available, including hydraulic, piston, shaft, wipers, buffers, wear rings, and custom-tooled.
Back-up rings work with an O-ring in higher pressure and temperature applications to prevent the O-ring from extruding into the clearance gap between sealing surfaces.
Lathe-Cut rings have a square cross-section profile, perform well in static applications, fit in O-ring grooves, and are interchangeable size-for-size with standard O-rings.
Oil seals, rotary shaft seals, and V-rings are used to seal in system fluids and lubricants while keeping out dirt and contaminants.
X-Rings have a four-lobed cross-section profile that provides twice the sealing surface of an O-ring, fit in O-ring grooves, and are interchangeable size-for-size with standard O-rings.
U-cups or Lip seals perform well in rod, piston, reciprocating, and some rotary applications. As pressure increases, the “U” shape self-energizes to maintain sealing effectiveness.
By definition, rubber diaphragms are flexible seals that prevent unwanted transmission of substances between two places. These substances can be liquid, gasses, or solutions. They are characteristically tough and dynamic and essential in many flow control applications.
Cord stock is O-ring material ready to be cut to create custom size O-rings. There is a large selection of cross-sections available and can be cut to any length you need or in standard put-up lengths.
Our rubber gaskets can seal items, stop vibration, and reduce noise pollution.
Custom parts can be anything from a unique shaped widget or just a standard style part (O-ring) with a non-standard set of dimensions.
