Macomb Group Approved 633D-SS10 Kamlok Coupler 1 in Fnpt

Product Description

The MACOMB GROUP APPROVED 633D-SS10 is a Series 633D Kamlok cam-and-groove coupling designed for fast, tool-free connections in fluid transfer applications. Built from 316 stainless steel, this female NPT (FNPT) coupler accepts a 1-inch male adapter with a 1-11/2 thread size. The outside diameter measures 1.83 inches, overall length is 2.47 inches, and coupler length is 1.62 inches. Cam arm spread is 2.91 inches closed and 5.03 inches open. Licensed plumbers, pipefitters, and industrial maintenance technicians commonly install this style of fitting in process piping and chemical transfer lines.

Series 633D couplers are well-suited for liquid and bulk fluid transfer in industrial, agricultural, and municipal applications. The FNPT connection allows direct threaded installation into standard female-threaded pipe, tanks, pumps, or hose assemblies. The 316 stainless steel construction makes this coupler appropriate for mildly corrosive media and sanitary or washdown environments where carbon steel or aluminum fittings are not acceptable.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber familiar with threaded pipe connections and applicable codes such as the IPC. Shut off and depressurize the line completely before installing or removing any cam-and-groove coupling. Apply thread sealant appropriate for the media being transferred to the FNPT threads before assembly. Inspect cam arms and gasket seating surfaces for damage before each use.
