The BSC PREFERRED 25301 is a viscous pipe thread sealant paste formulated for leakproofing threaded, flanged, and assembly line connections. The compound sets pliable and is nondeteriorating to PVC, making it suitable for both metal and plastic piping systems. It stays nondripping during application, which speeds up the work process and reduces mess. Plumbers, pipefitters, and HVAC technicians apply this compound to threaded joints before assembly to create a reliable, leak-free seal. The paste consistency allows for controlled, even application without running or sagging on vertical connections.
This sealant is appropriate for residential and light commercial plumbing and mechanical installations where threaded and flanged connections require sealing. It is well suited for assembly line connection work and field installations involving water supply lines, gas lines (verify local code compliance), and HVAC refrigerant or condensate piping. The nontoxic formulation reduces handling concerns during normal application. Joints sealed with this compound permit easy disassembly for future service or modification without damaging threads.
Designed for use on threaded and flanged pipe connections in plumbing and mechanical systems, including assemblies involving PVC fittings and components.
Apply this compound to clean, dry threads before assembling the joint. Pipe thread sealants should be applied by a licensed plumber or qualified mechanical tradesperson in accordance with applicable plumbing codes such as the IPC or local amendments. Shut off the water supply or relevant system pressure before disassembling existing joints for reapplication. Verify local code approval for the intended pipe service type, particularly on gas or potable water lines, before use.
