RaceFlux Dowty Bonded Sealing Washer, for BSP Threads

Seal a straight thread at the flange: this Dowty bonded sealing washer pairs a metal outer ring with a bonded rubber sealing lip, sealing under a fitting's flange as it tightens — the correct way to seal BSP parallel threads that don't seal on the threads themselves.

Key Features

• Bonded metal ring with rubber sealing lip
• Seals BSP parallel threads at the flange
• Cleaner and more reliable than thread sealant

Fitment & Compatibility

• Select the BSP thread size from the dropdown
• Common uses: BSP-ported coolers and components, adapter fittings, drain plugs
