Locking Air Hose Couplings
For a positive sleeve locking coupling system, we offer both the Thor type or Bowes type interchange, both of which offer positive locking mechanism and an increased pressure rating of 300 PSI. These two styles both combine the quarter turn claw style with a sleeve retractable feature of a quick disconnect coupling. Thor couplings do not have a male and female, they connect to themselves and are offered with sleeve lock or without (one sleeve lock per set is required, but connecting two sleeve lock couplings is possible). Bowes type do have a male head and a female socket, the sleeve lock is on the male nipple only.
Bowes style couplings are also known as Dix-Lock, N-Series, or MacDonald quick couplings.
Thor style couplings are also known as Dual-Loc, P-Series, or Thor-PHC quick couplings.
These two coupling types are not interchangeable with one another or with Chicago type universal couplings. Contact us for quotation or for further details.
