Part No.
Quick-test hose, 1/4" S.S. tube stub hose ends, 3 ft (92 cm) long
Hoses permit connections to Quick-test adapters, tube fitting quick-connects or NPT quickconnects
• Low volume reduces the pumping effort or compressed gas usage in pressure calibration
• No thread sealant required – connect adapters to without wrenches, thread sealant or thread tape
• Bubble tight connections to 6900 psi (375 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 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.
