Weatherhead T-420-29 Hydraulic Seal Washer Bonded Sealing Washer

The Weatherhead T-420-29 is a new bonded sealing washer (also known as a Dowty-style or bonded seal) consisting of a metal outer ring bonded to a synthetic rubber inner sealing element, designed to provide a leak-free face seal on hydraulic fittings and port plugs. The amber/orange-colored metal carrier ring is bonded to a black elastomeric sealing element, which compresses under torque to create a positive static seal against a flat machined surface. The part number suffix '29' in Weatherhead's T-420 series designates the specific dimensional size of the washer, and the product is intended for use with Weatherhead hydraulic fittings and threaded port connections where a reliable metal-to-metal-backed elastomeric face seal is required. This is a new, unused unit supplied in original Weatherhead packaging bearing part number T-420-29.
