How to order
ALWAYS specify gas or mixture to be used:
- select model e.g. HP1700, HP1701
- select material e.g. brass, stainless steel
- select inlet gauge: to match cylinder or line pressure e.g. GG (300 bar), GL (100 bar brass, 66 bar stainless steel), E (26 bar), U (13 bar)
- select inlet connection e.g. BS3, DIN 1
- select any inlet options e.g. body purge, cross purge, filters (pressure rating dependent)
- select outlet connection e.g. 1/4" compression fitting (standard), other fittings are available
- select any outlet options e.g. filters
