Spliced & Vulcanized O-Rings - Current typical lead time is 5-10 days for up to 10 O-Rings. More than 10 pieces may take 10-15 days depending on cord stock. 

Spliced and vulcanized o-rings are a great solution when standard o-rings cannot be used or cannot be purchased quickly. Spliced o-rings are made from extruded o-ring cord and then vulcanized to form the o-ring size (ID) required. The O-ring Store provides seamless spliced Standard Inch & Metric O-rings in all of the standard materials in a variety of cross sections, as well as Splicing Kits.

This process allows for custom sizes larger and different than standard molded o-rings.

Square O-rings - Square Cut Washer Rings

Square-rings are square cross-section seals designed to be interchangeable with standard AS568 O-Rings. Complete interchangeability within standard glands is assured in most applications.

Buna-N O-Rings 70 Duro (NBR):

The most commonly used elastomer for sealing products. Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum base oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties. The material performs well with most dilute acids, silicone oils and lubricants and in water applications. It is not recommended for use with ketones, aromatic hydrocarbons and phosphate ester hydraulic fluids. More than 50% of the Orings sold are Nitrile Orings, commonly used in hydraulic/pneumatic motors, cylinders, pumps and valves.

Buna-N / Nitrile Recommended uses:

  • General purpose sealing.
  • Petroleum oils and fluids.
  • Gasoline
  • Hydraulic fluids
  • L.P. gases
  • Cold Water.
  • Silicone greases and oils
  • Di-ester base lubricants (MIL-L-7808).
  • Ethylene glycol base fluids (Hydrolubes)

Nitrile is not recommended for:

  • Halogenated hydrocarbons (carbon tetrachloride, trichloroethylene)
  • Nitro hydrocarbons (nitrobenzene, aniline)
  • Phosphate ester hydraulic fluids (Skydrol, Fyrquel, Pydraul).
