Model Overview

This is a double check assembly. Production began in 1990.The 3/4"-2" size is a wye pattern glass filled noryl poppet style wye pattern check. The body is made of bronze. In 2010 the 950XL2 was introduced and made of lead free bronze. The rubber kit fits both versions. The check springs are not contained when the screw on cover cap is removed. There were three versions of check seats produced. The 950 version has a non-replaceable check seat. The model 950A had a replaceable bronze seat. The model 950 XL had a replaceable seat made of glass filled noryl. A seat removal tool was needed to change the seats. The check discs in the 950 XL were changed to silicon rubber. In 1997 a top entry model was created and called model 950 XLT. Another model, the 950 XLV, was created with union ends and 90 degree elbows on each end.
