(1) O-RINGS, SQUARE RINGS, QUAD SHAPED RINGS
TCK offers a complete line of compounds that are approved to every military and industrial specification.
Stock standard compounds include Brna-N (Nitrile), neoprene, EPR, silicone, flourosilicone, and flourocarbon (Viton). Also for others, as well as special sizes are available.
O-RING SQUARE RING QUAD SHAPED RING
(2) V-RINGS
The V-ring is an all-rubber seal. It mounts directly on the shaft and seals axially against the counter-face, housing, bearing race, and similar surfaces. Designed with a long flexible lip, it acts like a mechanical face seal and a lip seal. It can retain lubricants or exclude contaminants. The V-ring also can be used as the primary seal or as a secondary back-up seal. And it is capable of handing a greater amount of eccentricity and misalignment as well as axial movement. Each V-ring can be used for a range of different shaft sizes.
(3) WIPER RINGS:
For those extremely dirty rod wiping situations, a standard Polyseal can be used as a wiper ring.
Properly selected wiper rings will greatly extent the life of internal seals and bearings in hydraulic equipment.
(4) U-CUPS:
TCK offers a complete line of U-cups constructed of such diverse materials as homogeneous rubbers as well as leather and fabric reinforced rubber compounds. However, when you have an application that requires a special U-cup, TCK's Engineers are ready to work closely with your engineers in designing, tooling, prototyping and testing custom parts.
(5) POLY SEALS
The polyseals are a family loaded lip U-cups. Each style incorporates the use of a quad shaped rubber energizer to improve the low pressure, low temperature sealing characteristics of a fully molded polyurethane U-cup. Polyseals are available in a borad range of compounds including Fluorotrel, Nitrile, Fluorocarbon, and Ethylene Propylene Elastomer. Polyseals are available in extended range of diameters and cross sections. They seal a broad range of fluids including petroleum based hydraulic oil plus all fire retardant fluids such as phosphate esters and water glycol.
(6) PISTON CUPS
TCK offers a complete line of piston cups constructed of homogeneous rubber, urethane, cotton duck, rubber and other materials. The product can be supplied with a center hole to ensure concentricity between cup and piston or you may elect to receive them with no cener hole to adapt one stndard bore size and different piston hardware.
