valves

Hi, I've emailed Golem Gear, guessing they haven't picked up my email or I'm impatient! Looking to source the attached one way/flapper/mushroom valves. Don't appear to be on GG's website, so I'm assuming at some point new valve spiders [holders] are required to accept the clear style valves...

300 BAR Interspiro Valves Hi, looking for 300 BAR DIN Valves conical, LH/RH to suit Inspiro 4ltr tanks. If anyone has a pair they would like to part with, or something similar to suit (LAR valves), please PM me. Thanks in advance!
