Product Questions & Answers

What size BSPP fitting does this sealing washer work with?
Question by: Patty B on Feb 22, 2026, 6:46 PM
This copper sealing washer is made to fit a 1" BSPP connection.
Answer by: Customer Support on Feb 24, 2026, 6:12 PM
These the right washers for a 1 inch BSPP fitting? Got a connection that keeps weepin and need to sort it out.
Question by: Kurt P on Sep 24, 2025, 10:57 AM
For a 1" BSPP connection with G 1 - 11 thread sizing, these are the correct washers. At 40mm outer diameter and 1.4mm thick, they seat properly against that thread standard and give you the metal-to-metal seal that stops that kind of slow weeping leak. Just make sure the seating face is clean before you torque it down.

got a 1 inch BSPP connection, is this the right sealing washer for it?
Question by: Randy M on Apr 10, 2025, 5:12 PM
For a 1 inch BSPP (G 1 - 11) connection, this washer matches that size callout and is meant to seal that style of BSPP joint.
