Price: Per adapter
(if two shown for illustration purposes only)
A 10mm copper pipe to 21.8mm LH (Left-Hand) thread adapter is typically used for LPG, propane, or caravan/motorhome gas systems (such as connecting a 10mm copper gas line to a 21.8LH regulator or cylinder valve)
21.8mm LH x 10mm RH Brass Adapter: Specifically designed to bridge a 21.8mm left-hand threaded gas connection directly to a 10mm right-hand copper/compression side.
To adapt a 10mm copper pipe to a 21.8mm thread (commonly the W21.8 Left Hand thread used for LPG, Propane, and Butane gas cylinders or regulators), you will generally need a two-stage or modular fitting setup.
