PRESSURE RELIEF FITTINGS

• Fittings open at predetermined pressures to allow gear boxes, bearings and other closed systems to vent.
• Protects seals from catastrophic blow out failure.          

ONE DIRECTIONAL FLOW

• Internal check valves open to allow internal pressure to be vented from the system while not allowing external air to enter.

QUICK IDENTIFICATION

• Relief fittings are stamped with the upper pressure limit on the side of the fitting.
