The rubber coupling with stainless steel clamps on each side of the check valve allow for quick and easy connection to SCH40 PVC. It can spliced into an existing line very easily as well. It is also designed to be used in either a vertical or horizontal orientation. The full-flow design of this check valve allows the internal flapper to open to match the internal diameter of the connected line.
