Hydraulic & Pneumatic Seals
Hydraulic & Pneumatic Seal, hydraulic seal is widely used to assist in the operating of all type of equipment. Use of either oil or water is called hydraulics and for air or gas is called pneumatics. Crown Rubber Works offers a wide range of hydraulic and pneumatic products that are of premium quality and lasts long. Piston Seals, Rod Seals, Wiper Seals, Guide Seals are only few examples.
Custom Moulded Parts
We are one of the premium manufacturers of Custom Moulded Parts in the industry. We offer wide range of moulded parts for diversified applications exactly as per the requirements of our clients. The products are of superior quality and long lasting. They are Rubber Diaphragm, Rubber Boots and Rubber Gasket Products etc.
Rubber Bellows & Boots
We produce rubber bellows that are manufactured from different types of polymers. They are normally used as covers on parts which are critical and need protection from dust. Bellows are flexible types and have good cushioning properties. These are available in different shapes and types depending upon the fitment application.

We have extensive knowledge and experience in the design and manufacture of rubber products such as rubber bellows, grommets, pads rubber moulding etc. We supply products for a wide variety of applications including automotive, marine, white goods, rail, mining, hospital and institutional, materials handling, hardware, general engineering, building and construction, plumbing, Pumps, defense, food industries and so on.
Rubber Gasket
We produces all types of gasket as per requirement in NBR, SBR, EPDM, Silicon, Viton, NR and Special
types of gasket are available on request.
Basic Raw Materials
The most common nitrile copolymer blend is the compound known as Buna-N. It has a very good
resistance to petroleum based hydraulic oils, Buna-N and also works well with fuels like diesel or gasoline.
Nitrile seals have a good resistance to compression set, but their flexibility suffers to some extent in the
lower temperature range. The seals made from the material have a low resistance to ozone and must be
stored carefully in most of the environments. The working temperatures are -40° to + 240°F.
Ethylene-Propylene is used for sealing phosphate ester hydraulic fluids like Skydrol. It is not suitable for
petroleum based fluids, but is highly effective for use with steam, acetone, dilute acids and alkalies.
Specially compounded, it can be made suitable for automobile brake systems. The temperature ranges
from -20° to + 300° F.
Silicone is an elastomer that is made from silicon, oxygen, hydrogen and carbon. The main use of this
material is in static seals employed in a wide (- 75° to + 450° F) range of temperatures. It has high
resistance to dry heat, ultraviolet light and ozone. This material is not recommended for dynamic
situations due to poor abrasion resistance and high friction characteristics.
(VITON is the register trademark of DuPont Dow Elastomer). Fluorocarbon combines high temperature
resistance with an excellent chemical resistance. It is excellent for use with alcohol and aromatic fuels
and highly resistant to ultraviolet light and ozone. This material is not recommended for the use in low
temperatures or in aircraft hydraulic fluids. Its temperature range is – 20° to + 400° F.
