ABSTRACT:
A pipe coupler for use in fire sprinkler systems is of generally cylindrical shape. The coupler carries locking springs to engage grooves carried on the ends of the sprinkler pipes. The coupler also carries seal rings to provide for leak proof coupling. The locking springs are carried in grooves which have sidewalls which are perpendicular to the inner surface of the coupler. The corresponding grooves on the pipes also have sidewalls which are perpendicular to the exterior surface of the pipe.
