Thread these fittings onto your testing equipment by hand for a secure connection in testing applications—no tools, tape, or sealant required. Use them with gauges and other equipment as a temporary connection. When pressure is applied, the O-ring on the outlet presses against the testing equipment, creating a tight seal.
Adapters with intermittent swivel rotate 360° until tightened for easy installation.

Pressure Gauges for Hydraulic Jacks

Monitor hydraulic oil pressure levels to guard against overload. These gauges are liquid filled to reduce needle vibration and include an adapter to mount the gauge in line with the hose.
