Standard couplings
HFC12
The HFC12 series reaches flow comparable to many 1/2" couplings in a 3/8" body. These light polypropylene couplings with EPDM seals replace heavy metal ball-and-sleeve couplings. An efficient valve gives high flow and low spillage on disconnection, and the series is rated from vacuum to 4.2 bar and from 0 to 71 °C.

Frequently asked questions
- What advantage does HFC12 have over metal couplings?
- It is much lighter and more compact than metal ball-and-sleeve couplings, while its 3/8" body offers flow comparable to many 1/2" couplings.
- What pressure is the series rated for?
- From vacuum to 4.2 bar at 0 to 71 °C.
- Which hose sizes fit?
- Hose barbs are available for 9.5 mm, 12.7 mm, 15.9 mm and 19.0 mm hose, compression fittings for 9.5 mm and 12.7 mm OD tubing.
- How is the coupling operated?
- With a large, shrouded thumb latch pad that is easy to grip and works with one hand.
