Custom Hoses

Hoses permit connections to Quick-test adapters, tube fitting quick-connects or NPT quick-connects

  • 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 (brass) or 11,040 psi (stainless steel) with no moving parts
  • 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
  • Made in U.S.A.
