Pressure relief valve for PLAS-LABS glovebox

Useful for eliminating unwanted positive pressure build up in any of Plas-Labs® glove boxes. The acrylic relief valve is easily mounted at the gas inlet or outlet with 1/8 in. NPT SS connections. Exhausted air can be directed away from operators by a hose connection to the outlet port. For minimizing gas consumption, use with the controlled purge system.
