The KPC-179B Locking Collar is a cast-iron pipe clamp fitting for 48.3 mm OD, 1-1/2" Sch. 40 pipe. It wraps around pipe as a stop ring or removable support collar, using internal hex screws to lock the pipe without welding so structural pipework can be assembled, adjusted, and serviced on site.
Why It Matters
The black finish helps visible pipe structures sit quieter in scenic, retail, and event environments while preserving the corrosion-resistant hot-dip galvanized base treatment.
Key Features
Stop-collar function supports another connector or rotating joint from below.
ASTM A197 cast iron body supports demanding modular pipe structures.
Double-layer hot-dip galvanization helps protect the fitting in indoor and outdoor service.
Internal hex screws secure the pipe without welding, keeping the assembly relocatable.
Applications
