  • Connects Female NPT to Quick-test hoses with brass or stainless steel hose ends.
    • Ideal for connecting to pressure transmitters or other devices under test using thread sealant
    • Quickly connect and disconnect Quick-test hoses for testing, calibrating and sampling
    • Made in USA
  • A removable cap provides easy access to connect a Quick-test hose to the process for calibration purposes and is easily sealed bubble-tight again when calibration is complete
    • Connect to pressure transmitters, EFMs, Flow Computers and other NPT devices under test using thread sealant for a permanent connection
    • A Cap and chain makes calibration easy and quick by connecting and disconnecting a hose without a wrench or thread sealant
    • Made in USA
  • Quick-test Hoses

    $50.60$606.00
    Microbore hoses that provide a very quick, low volume, high pressure way of connecting to any pressure instrumentation, hand pump, calibration source or device under test
    • Low volume reduces the pumping effort or compressed gas usage in pressure calibration
    • No thread sealant required – connect to adapters without wrenches, thread sealant or thread tape
    • Bubble tight connections to 6900 psi (475 bar) with no moving parts reduces maintenance to almost zero
    • Hose is hard to break and very flexible
    • Adapt from hose to virtually any device under test with only one connection
    • Silver color dramatically reduces the effect that changing temperature has on pressure stability
    • A corrosion resistant strain-relief on each hose end reduces wear and dramatically increases hose life
    • Hose is excellent for inert gas applications (except Helium and Argon)
    • Hose is pin-pricked for use in Natural Gas applications
    • Made in U.S.A.

    The Crystal XP2i is The World’s Most Popular Test Gauge! The Crystal XP2i is Ultra rugged, intrinsically safe, digital test gauge and is available with 0.1% of reading, 0.02% of full scale, or 0.05% of full scale accuracy levels.
  • Connect a Quick-test hose directly to a DP transmitter using the bleeder port when the transmitter is not mounted on a 3 or 5 valve manifold or when the manifold is not easily accessible. This unique fitting makes a metal to metal seat on the transmitter and a Quick-test hose can be attached on the other side Connects through the bleeder screw port on a DP transmitter Made in USA
  • Make a bubble-tight connection to any Swagelok, Parker, Hoke, SSP, Tylok or equivalent tube fitting without a wrench
    • An excellent solution for connecting to tube fittings for pressure calibration, gas sampling, pressure reading and testing
    • A unique design that seals on an o-ring to prevent damage to a tube fitting
    • Make and remake hundreds of times without over-tightening a tube fitting
    • Made in USA
  • Connect to a pressure gauge or other device with Male NPT connections to a Ralston hand pump or nitrogen calibration device
    • Install with thread tape once onto any male NPT pressure gauge then use the Quick-test connection to quickly connect or disconnect from any Ralston hand pump, nitrogen calibration device or other Quick-test adapter
    • Saves the threads on a pressure gauge by not needing to make and remake the connection with thread sealant
    • Made in USA
  • Quick-test Unions

    Connect two Quick-test hoses or two Quick-test adapters together, depending on the union Quick-test connection makes connecting two hoses together quick and easy Made in USA
  • CPF Fittings and Hose are a new line of quick-test pressure fittings for calibration and test applications -- designed with an emphasis on safety. Crystal Pressure Fittings (CPF) perform up to 15 000 psi / 1000 bar, and feature a safety weep hole to alert you before you accidentally disconnect from a pressurized system. It can also be used as a bleed point. Each fitting is machined in 316 Stainless Steel and laser markings indicate the fitting type, size, part number, and Maximum Allowable Working Pressure to prevent a mismatched connection. An industry-first patented o-ring connection allows CPF Fittings to maintain a leak-free seal up to 10 000 psi with only finger-tightening. This offers an alternative to commonly-used NPT Fittings, which require technicians to wrap their fittings in thread tape and use a wrench to tighten each installation. Unlike other quick-change fittings, the O-rings in CPF Fittings are also easily replaceable. CHECK ITEM DESIRED AND CHOOSE QUANTITY TO THE LEFT OF LINE ITEM FOR EACH ITEM THAT IS BEING ORDERED
