OSK™ SAE Boss O-Ring Seal Kit

The 900 series of dash numbers identifies the 20 sizes of boss seals. Except for size -901, the digits after the 9 identify the nominal tube size in 16ths of an inch. The tube size is its outside diameter (OD). For example, size -903 is intended for use with 3/16-inch tube. The one exception, size -901, is intended for use with 3/32-inch tube. 1/16-inch tube is not common in aircraft use.

This Kit contains 250 pieces and 12 of the most popular 900 series O-Rings. These Boss Seal O-Rings are used in sealing straight thread tube fittings (Boss Type) in the design and service of hydraulic equipment.

Chemical Resistant and High Heat Fluorocarbon FKM O-Rings 90 Durometer:

Fluorocarbons (FKM) – commonly referred to as Fluorocarbon FKM, has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Fluorocarbon FKM has a temperature range of -20F to +400F, and provides excellent resistance to a wide variety of chemicals, weather and compression set requirements. The relatively high level of fluorine in Fluorocarbon FKM materials allows for exceptional resistance to chemical attack, but with limited low temperature capabilities.
