Reid Vapor Pressure Gauges
Ruggedly constructed Bourdon type gauges designed especially for the Reid Vapor Pressure test. These precision instruments feature a heavy duty rotary brushed stainless steel movement housed in a lightweight aluminum case with corrosion-resistant finish. Each gauge is equipped with a heavy duty brass non-sparking handle, blow-out disc, and 1⁄4" NPT male thread connection.
Features

Reid Vapor Pressure Test Cylinders
Polished stainless steel test cylinders designed for vapor pressure tests of liquid petroleum products, volatile crude oil and liquefied petroleum gas (LPG). Each cylinder consists of upper chamber and lower chamber in the required 4:1 volume ratio. O-ring gaskets provide tight seal between chambers and at gauge coupling.
The one-opening type is for gasoline and other products having a Reid Vapor Pressure below 26psi (180kPa). The two-opening type is for liquid products having a Reid Vapor Pressure above 26psi (ASTM D323) and for LPG (ASTM D1267). Lower chamber of two-opening apparatus includes straight-through ball valve and 1⁄4" needle valve. For LPG testing, order two-opening type apparatus and accessory bleeder valve assembly.
