 NPT Male Inlet × NPT Female Outlet Adapter with Intermittent Swivel |  NPT Male Inlet Plug |
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 Test Fittings
Steel
Check pressure without permanently installing a gauge. Fittings have an NPT male connection for installation in your pipe or tank. Wrench-tighten the fitting onto your equipment, then insert the gauge adapter (sold separately) into the fitting. Connect gauge adapters to gauges with 1/4 pipe size NPT male threads.

Gauge Guards
316 Stainless Steel Guard
316 Stainless Steel Guard With Drain Port
Also known as isolators or diaphragm seals, these protect gauges from corrosive process media. Fill guards with ISO Grade 32 hydraulic oil (not included) before use.
316 stainless steel guards provide excellent corrosion and chemical resistance and can handle higher temperatures and pressures than plastic guards.
Guards with drain port allow you to remove process media.
