【Reliable Sealing Function】These bonded seal washers combine a metal outer ring with a centrally molded rubber insert, designed to compress and form a seal around the threads of bolts, plugs, or fittings. This action helps prevent the leakage of fluids like oil, water, or air at connection points in various mechanical and plumbing systems. 【Comprehensive 8-Size Kit】The set includes a practical range of sizes: M6, M8, M10, M12, M14, M16, M18, and M20. This variety covers many common metric bolt and port sizes, making it a versatile kit for different tasks around the workshop, vehicle, or home without needing to source each size individually. 【Suitable Material Composition】The washers are constructed with a metal ring for structural support and an integrated rubber sealing ring. The rubber compound is formulated to perform in the presence of oils and greases, maintaining its sealing capability in environments where it contacts such media. 【Ample Quantity & Storage】This bonded seal washers for hydraulic fittings assortment provides a total of 110 pieces across the eight sizes, with higher counts for commonly used sizes like M12, M14, and M16. The included plastic storage box with compartments helps keep the different sizes separated and easily accessible for your next repair or maintenance job. 【For General Maintenance Use】This kit is intended for mechanics, technicians, and DIYers working on automotive engines, hydraulic lines, industrial equipment, or plumbing fixtures where a reliable threaded seal is required. The washers serve as replacement parts to help address leaks or as preventative seals during assembly of fluid and pneumatic systems.
