DuraChoice's oil-filled gauges are known for their quality and these lower mount pressure gauges are no exception. 

Although these are the smallest liquid filled gauge DuraChoice makes, they are designed for reliability and readability.

A stainless steel case and poly-carbonate window protect the liquid filled 1 1/2" face in harsh conditions. The connection, movement and bourdon tube are copper alloy (brass). This gauge is available in pressure ranges from Vacuum-0 PSI to 0-15,000 PSI. These oil filled gauges are good for water, oil, gas (WOG) and diesel.
