Brass Pin-Lug Swivel Coupling
The Value Brand 1-1/2 inch FNPT by FNST brass coupling connects a female NPT thread to a female NST thread. Its pin-lug swivel design allows the connection to rotate freely during installation and use. Fire-service and industrial plumbing crews use it to join hose lines or equipment with mismatched thread standards. The rough-finish brass body resists corrosion in wet environments.
Swivel Action Under Pressure
The internal swivel mechanism rotates on a brass-on-brass bearing surface while the joint remains pressurised. Pin lugs on the exterior give a secure grip for hand tightening without tools. Because the swivel is integral to the fitting, there is no separate rotating joint that can loosen under vibration or thermal cycling. The straight body keeps the flow path unrestricted.
FNPT-to-FNST Thread Compatibility
The single specification that decides fit is the pairing of a 1-1/2 inch female NPT thread on one side and a 1-1/2 inch female NST thread on the other. If the mating components use any other thread standard or size, this coupling will not seal. California Proposition 65 warnings apply to the brass material.

Questions about this item
Does the brass construction of the 1-1/2 in swivel coupling generate heat or noise during continuous water flow?
The brass-on-brass swivel operates silently and does not generate measurable heat during normal water-flow operation.
Which thread standards must my existing hose and pipe already have to connect this FNPT x FNST adapter?
One side requires a 1-1/2 in male NPT thread and the other a 1-1/2 in male NST thread for the pin-lug swivel to engage.
Will the rough-finish brass coupling thread reliably onto older galvanized or stainless pipe threads of the same nominal size?
The NPT and NST threads follow standard taper and straight profiles, so they mate with existing 1-1/2 in pipe threads of matching specification.
