Fischer & Plath Aluminum Seal Ring Washer Gaskets & Seals

Fischer & Plath aluminum seal ring washers, also called aluminum crush washers, sealing washers or gaskets, make a leak-tight seal at threaded fittings. They are commonly used on drain plugs, sensors, switches, and chain tensioners. The soft aluminum compresses between the fastener and its mating surface. It fills small imperfections and helps keep oil, fluid and pressure in.

Key Features:

• Compressible aluminum construction conforms to the sealing surface for a reliable static seal
• Precision-machined and stamped flat rings for consistent thickness and even sealing contact
• Versatile applications include drain plugs, temperature sensors and switches, and timing chain tensioners
• European-engineered quality from a company that specializes in machined seals, plates, shims, and precision stamped metal parts

Crush washers are designed for single use. Replace the washer whenever the fastener is removed, because a washer that has already been compressed will not reseal properly. Choose the correct inner diameter, outer diameter and thickness for your application from the variants listed.
