0.45mtr W20 x W20 Pigtail

This WILL NOT work as a pigtail between a Gas bottle / Gas tank outlet tap and a regulator or change over valve.  If you want a normal pigtail for use from the bottle outlet tap ( 21.8LH ) to the regulator/ change over valve ( W20 ),  you need to buy W20 x 21.8 Lh pigtail listed elsewhere on the GAS IT webshop.   

This is a GAS IT 0.45mtr pigtail hose with W20 x W20 fittings on both ends which is used between the Gas regulator ( W20 ) and a changeover valve ( W20 ) to allow the changeover valve to be positioned remote from the gas regulator. ( when space in your gas locker does not allow direct mount regulator / changeover valve)
