BOSS O-RING KIT

Typically, boss seal O-Rings are designated for hydraulic applications, specifically for sealing straight thread tube fittings in a boss. The AS568 specification sites specific sizes for boss O-Rings, designating them with "900" series numbers. The Boss O-Ring Kit includes 212 O-Rings in all of the twenty AS568 sizes. The solid grey plastic styrene box features post and recess style O-Ring retention. The kit also includes a brass O-Ring extraction tool. There are two different materials to choose from depending on the application: 90 durometer nitrile or 90 durometer fluorocarbon.
