Gas Can Opener Valve HS-339

Description

Product DescriptionThe Hongsen HS-339 (also widely designated as the CT-339) is a heavy-duty, manual pin-type fluid dispensing valve designed for HVAC/R technicians and automotive mechanics. Machined from premium solid brass for exceptional corrosion resistance and a leak-free seal, this tool provides a secure, regulated connection to small, disposable refrigerant canisters.It features an ergonomic, impact-resistant green handwheel that controls a high-strength internal piercing needle. When screwed down, the needle cleanly punctures the top of the can, and the built-in rubber gasket seals tightly against the canister neck to prevent gas loss. The angled side-discharge port allows for an easy, unrestricted connection even in tight working spaces.Technical SpecificationsBrand: Hongsen (also distributed as generic CT-339)Model: HS-339 / HS-339A (Green Pin Type)Material: Solid Brass body with a composite adjustment knobInlet Connection: Specially threaded for standard R134a style small canisters (typically $M14$ thread)Outlet Port: 1/4″ SAE Male Flare (compatible with standard charging hoses)Mechanism: Manual screw-down piercing pin with a heavy-duty internal rubber seal ringModel Variations & EquivalentsThis tool belongs to a standard family of refrigeration openers.
