This GAS IT designed and manufactured heavy duty brass fitting with knurled grips on the side comes with a Male W21.8 thread at one end which is designed to go directly into a UK Autogas Bayonet fillpoint and on the other side of the fitting there is a Female 1/4"BSPT threaded hole which will take any 1/4 BSPT fitting - like our GAS IT reserve hoses.
It has many possible uses in the LPG industry and being brass with high quality knurling on the side means its easy to screw directly into UK Autogas fillpoints.
