Lathe cutting rubber washers and rubber gaskets is the process of inserting a mandrel into an extruded rubber tube and cutting the finished dimension with a knife while the mandrel is being turned at high speed in a lathe. We use state-of-the-art lathes and grinding equipment to finish the outer surface to precise tolerance.

Some of the advantages of lathe cutting are no tooling cost, minimal waste, no flash, no die-cut concavity (hour-glassing), and an excellent static face sealing surface.

Thomas A. Caserta, Inc. has been a leading manufacturer of lathe cut rubber gaskets, rubber washers, rubber seals, rubber bushings, rubber sleeves, and rubber rollers for over 60 years.

Materials Used

Materials Used

N/A
These are the most common material but we are not limited to them:

Ethylene Propylene Diene Monomer (EPDM) - Excellent weatherability, good high and low temperature resistance, low gas permeability. Resistant to ozone, steam, water, alcohols, brake fluids. Poor resistance to petroleum oils, diester lubricants. Temperature range: -60°F to 280°F.

Neoprene - Good general purpose elastomer, with moderate oil, ozone and water resistance. Resistant to freons, high aniline points oils, mild acids. Not recommended for phosphate esters, ketones, brake fluids. Temperature range: -65°F to 260°F.

Nitrile - Excellent resistance to petroleum products, excellent compression set; resistant to oil, water, silicone greases and oils. Not recommended for halogenated hydrocarbons, ketones, ozone and sunlight. Temperature Range: -65°F to 275°F.

Styrene-Butadiene Rubber (SBR) - General purpose elastomer, good adhesion to various substrates, good abrasion resistance, good resiliince. Resistant to brake fluids, alcohols, water. Not recommended for solvents, oil/gas, sunlight. Temperature range: -65°F to 225°F.

Silicone - Best overall temperature range of elastomers currently available. Excellent resistance to dry heat, as well as, resistance to low temperature, brake fluids, high aniline point oils. Not recommended for some dynamic applications due to poor tensile strength and tear. Poor in petroleum oils and ketones. Temperature range: -150° to 500°F.

Viton® - Outstanding resistance to the effects of heat, chemicals, and solvents. Viton® has good tensile, resistance and low compression set. Limitations include poor low-temperature properties, limited hot-water resistance and shrinkage. Temperature range: -50° to 600°F.
