V-Packings are multiple-lib (chevron) seals comprised of a group of endless rings and are popular for sealing rods and pistons. They can be used for low or high pressure applications and with sing or double acting cylinders.We presently stocks in fabric reinforced nitrile and V-Rings (centre rings) in fabric reinforced nitrile. In general, fabric V seals are for high pressure, and homogeneous V seals are for low pressure. The selection of fabric or homogeneous compounds should be made on the basis of operating pressure, temperature, and the type of gaseous or fluid medium with which the packing must function.

Vighnesh Rubbers designed lined seals are ideal for dental cartridges and pen delivery systems, such as those used for injectable insulin. The seal liners are available in a variety of standard rubber formulations. Proper rubber formulation selection is the key to a safe and successful product. When a standard formulation does not meet the needs of a unique application, Vighnesh Rubbers formulation development capabilities are available for custom solutions.

U-Cups seals derive their name from their shape and are self-sealing on both the inside diameter and outside diameter. They are most often used for sealing rams or rods and are very popular due to the small gland space required. They are especially adapted to low speed, low pressure environments for both pneumatic and hydraulic cylinders. They provide an extremely smooth, steady movement because of their inherent low friction.The seal is obtained by means of the flared, flexible libs coming in contact with the rod or cylinder wall. Clearance is provided at the heel for minimum friction. Through this design, the packing is preloaded when installed. Sealing effectiveness is increased by internal pressure of the air or fluid (hydraulic seal) against the inner surface of the libs. For continued sealing effectiveness and long seal life, the surface finish of the working surface of either rods or bores should be a maximum of 16 micro-inches. It is not recommended that U-cups or any other single lib seal be used in any application where there is excessive side loading.

This window rubber seals are suitable for fitting either Perspex, glass or acrylic into boats, cars, vans etc. It allows for easy replacement of damaged windows. To find your required size measure your glass and panel thickness. The rubber will seal approx -1mm (e.g. 4mm glass will seal in a 5mm gap). It is recommended to bed the rubber in with a silicone sealant.
