DIRECT FIT — CGA-320
Typical standard: CGA-320 (0.825″-14 NGO, RH).
If your valve is marked CGA-320, our regulator typically threads on directly (no adaptor, no stem swap).
CONDITIONAL — BS 341 No.8 (often same physical family as W21.8 × 1/14)
What you need: a local nut + stem compatible with your cylinder outlet that ends in ¼″ NPT RH at the regulator.
Reminder: confirm markings or measure OD to be sure (imports happen).
CONDITIONAL — W21.8 × 1/14 (DIN 477 No.6 / BS 341 No.8 equivalents)
What you need: a local nut + stem for your cylinder outlet that terminates in ¼″ NPT right-hand male threads on the regulator side.
Hard rule: if the stem does not terminate in ¼″ NPT RH, it will not fit our regulator body.
CONDITIONAL — ~W21.7 × 1/14 (France / Spain / Italy family)
Very close to W21.8 but not always identical. Confirm markings or measure carefully.
What you need: a local nut + stem that terminates in ¼″ NPT RH on the regulator side.
CONDITIONAL — JIS / W22 × 14 (Japan / Taiwan / Korea)
Local nut + stem required. Confirm JIS markings and ensure the stem terminates in ¼″ NPT RH.
CONDITIONAL — AU/NZ Type 30
Local Type 30 nut + stem required, terminating in ¼″ NPT RH.
CONDITIONAL — G5/8 BSP Family (China / Argentina)
Varies by supplier and gas service. Contact support with valve photos and markings before attempting adaptation.
CONDITIONAL — Mixed Markets (Peru / Brazil)
Some suppliers resemble CGA-320; others resemble industrial BSP families. Confirm markings or measure OD.
HIGH RISK — Russia/CIS & nearby (confirm before attempting adaptation)
Regional fittings vary and may not match common DIN/BS families. Contact support with front+side valve photos and any markings.
