Each size is a package of 50 rings how it works U.S. and Foreign Patents Pending SoluGap™ is the most stable water soluble socket welding spacer ring, with unique patent-pending tabbed edges to keep the spacers stable for effective joint socket alignment. The Design Solution SoluGap™ has uniquely engineered 3-point tabs around the edges to hold it in place, even when the socket is sideways or upside down. A hollow center allows you to view inside the pipe easily during socket welding. SoluGap™ is solid, yet completely water soluble. The Productive Solution Eliminate the need to pre-measure or guess the size of a gap opening before welding, SoluGap™ provides the 1/16" minimum gap required by ANSI 31.1, Section III, ASME, US Navy & Military Codes. SoluGap™ is easy to install and ready to use. Just snap in and weld! Unlike other spacers, SoluGap™ dissolves completely and does not corrode. SoluGap™ costs less and performs better ... It’s the economical solution!
