Fittings & Adapters

Quick-test adapters, fittings, elbows, tees, manifolds, fluid traps, and Crystal CPF — the connection hardware that makes pressure calibration kits leak-tight and repeatable.

Why fittings matter

Most calibration delays come from leaks and mismatched threads, not from the gauge. Matched Quick-test / CPF hardware lets you rebuild a setup without wrenches and without damaging soft seals every time you change a UUT.

What we stock

• **Quick-test adapters** — hose-to-NPT, AN, tube, and process connections (Ralston QT/QTHA families).
• **Elbows, tees, and manifolds** — benchtop and field distribution of pressure.
• **Fluid traps** — protect gauges and controllers from liquid carryover.
• **Crystal CPF** — Crystal’s proprietary fitting system for many Crystal gauges and modules.
• **Kits** — common adapter assortments for field techs.

Pairing tip

Match the hose and adapter family to the pump and gauge on the product page. OEM-paired accessories are listed under Related products when we have datasheet-backed pairing.

Note

Fittings are typically not ISO/IEC 17025 calibrated; calibrate the **gauge or calibrator** in the loop.
