InstantAir Steel Range · Pneumatic Fittings
7.9mm (5/16") Steel Quick-Release Air Coupling
with Integrated Hose Tail
Precision-engineered for compressed-air systems that demand reliability under pressure. Broomwade-profile interchangeability, 17 bar rated, and built from solid steel for a working life measured in decades — not seasons.
Overview
This InstantAir coupling is the professional's choice for 7.9mm (5/16") internal-diameter air hose. The integrated hose tail seats directly into the hose bore, while the knurled quick-release sleeve delivers one-handed tool changes without interrupting workflow. Manufactured from solid steel with a metallic finish, it is equally at home on a busy workshop airline or a precision industrial rig.
Rated to 17 bar (250 psi) and capable of 54 cfm at 100 psi, this coupling handles the demands of high-volume pneumatic tools — from impact wrenches and spray guns to tyre inflation and blow-off equipment.
