What it is

The Saunier Duval 0020193804 Adapter, G1 x G3/4, is a threaded reducing adapter used to join a G1 (1 inch BSP) connection to a G3/4 (3/4 inch BSP) connection. It is a general plumbing consumable rather than an appliance-specific component, and is supplied under Saunier Duval part number 0020193804. Its function is to bridge two different thread sizes within a heating or water circuit.

Before you order

  • Confirm both thread sizes on the installation match G1 and G3/4 before ordering.
  • Check whether a flat-face or tapered sealing arrangement is required at each connection.
  • Verify the adapter part number against the appliance or installation documentation.
  • Consider whether a sealing washer or jointing compound is needed to complete the joint.
