419 Pcs Metric O-Ring Assortment Kit, 32 Sizes, Buna-N 70A

This 419-piece kit holds metric O-rings across 32 sizes, with inside diameters from 3 mm to 50 mm. Each size sits in its own labeled compartment, and a size chart lists the dimensions for every ring so you can match a worn seal before opening the case.

The rings are made from Buna-N, an NBR nitrile rubber rated at 70 Shore A. They are suited to hydraulic, fuel injector, faucet, pneumatic and pressure washer applications, and the molded red case has a snap lid to keep the rings contained.
