SMC KQ2H03-07A push-fit fitting 5/32 in

SKU CH-W3BC-22X1K

A push-to-connect fitting for 5/32 in tubing handles air or water up to 150 PSI and -20 to 140 °F with a one-touch metal design

  • One-touch design speeds up pneumatic hose connections
  • Metal construction handles 0 to 150 PSI air and water lines
  • Dual chuck mechanism seals reliably across the pressure range
  • Operates from -20 °F to +140 °F in demanding environments
  • Push-to-connect both ends simplifies 5/32 in tubing installation

SMC KQ2H03-07A push-fit fitting 5/32 in

The SMC KQ2H03-07A is a push-on hose fitting built for fluid plumbing in pneumatic systems. It connects and disconnects hoses using a one-touch design that speeds up installation and removal. The metal construction includes a dual chuck mechanism for a reliable seal. This component suits technicians and engineers who need quick, repeatable connections for air or water lines.

One-touch metal fitting for pneumatic builds

The fitting joins two push-to-connect ports sized at 5/32 in, slotting directly into existing tubing runs without tools. Its metal body handles operating pressures from 0 to 150 PSI and temperatures from -20 to +140 °F, so it fits systems that cycle through wide thermal ranges. The dual chuck design frees up assembly time by removing the need for clamps or thread sealant on each joint.

Replaces threaded or barbed connectors

Swapping older threaded or barbed fittings for this push-fit model cuts connection time and reduces leak paths at each joint. The upgrade is worth it when maintenance intervals are short or when tubing must be rerouted frequently. It is not suited for fluids outside the stated air and water compatibility or for pressures beyond the 150 PSI ceiling.

Questions about this item

What is the maximum pressure the KQ2H03-07A can handle before the seal becomes the limiting factor?

The dual-chuck mechanism is rated for an operating pressure range of 0 to 150 PSI, so sustained use above 150 PSI would exceed the sealing limit.

How much heat can the metal fitting tolerate during continuous all-day pneumatic operation?

The fitting's operating temperature range is -20 to +140 °F, so the metal construction remains within spec as long as the system fluid stays below 140 °F.

What tubing size must I already have on hand to use this 5/32 in push-to-connect fitting?

You need 5/32 inch (approximately 4 mm) outside-diameter tubing compatible with air or water service for both push-to-connect ports.
