Due to having a higher density, Viton has the widest temperature range of -40°F to over 400°F (-40°C to over 240°C) making it a perfect choice for higher temperature applications. Viton® also has the largest range of chemical resistance, i.e., it is resistant to silicone oil and grease, mineral/vegetable oil and grease, aliphatic, aromatic, and chlorinated hydrocarbons, non-flammable hydraulic fuels as well methanol fuels, and more.
Furthermore, neoprene foam gaskets offer superior insulation properties
. The foam material has a low thermal conductivity, which helps to reduce heat transfer and maintain temperature control in applications where thermal insulation is critical. This makes neoprene foam gaskets suitable for use in HVAC systems, refrigeration units, and other applications where thermal management is essential.neoprene foam gasket

The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
The skeleton oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension.
One of the primary advantages of natural rubber gaskets is their excellent sealing properties. Due to their inherent elasticity and compression set resistance, natural rubber gaskets can effectively conform to irregular surfaces, creating a tight seal that prevents fluids or gases from leaking. This is especially important in industries such as automotive and aerospace, where even the smallest leak can lead to catastrophic consequences.
Silicone compounds or “VMQ” offers a wide range of traditional operating temperatures starting at -60°C to 200°C (-140°F to 392°F).

Oil Seal Installation Guide
Outstanding resistance to mineral oils, aliphatic and aromatic hydrocarbons, as well as CHCs, concentrated and diluted acids, and weak alkalis. Excellent resistance to high temperatures (up to 200 °C) and a low temperature resistance down to -40 °C depending on the type used as well as good mechanical attributes and an exceptionally good ageing resistance make FPM a cut well above the usual synthesis natural rubbers.
2) Oil seals for steel production equipment
Installation techniques must be carefully selected and executed to ensure the seal functions correctly throughout its service life. Each technique addresses specific installation needs and ensures long-term reliablity.
Where loads are light, the outer skin layer can be made of silicone. It can be made of Fluroelastomer (orViton) to protect under high temperatures (more than 120 degrees Celcius). The skin can also be made of Poly Acrylate or Polytetra-FluroEthylene.
