Shank Coupling for 1 1/2 in NPSM Hose
This aluminium shank coupling connects 1 1/2 inch NPSM hose ends in a plug configuration with a swivel joint. The female and male fittings share the same 1 1/2 inch size and thread standard. It is built from ADC12 aluminium for corrosion resistance in compressed-air and fluid-transfer systems. The component is supplied new and ready for installation.
NPSM thread limits and chemical warning
National Pipe Straight Mechanical threads seal on a gasket or washer rather than on the threads themselves, so a compatible sealing element must be present for leak-free operation. The straight-thread design does not create a taper seal, limiting use to applications where a flat-face or gasket seal is specified. California Proposition 65 notices indicate the product contains a chemical known to cause cancer and a chemical known to cause birth defects or other reproductive harm.
Replaces worn or mismatched aluminium couplings
This coupling replaces damaged, corroded or incorrectly threaded aluminium fittings on 1 1/2 inch hose assemblies using NPSM connections. The upgrade is worth it when the existing fitting leaks at the swivel, shows thread deformation or fails to maintain a seal under system pressure. It is not suited for installations requiring tapered NPT threads, larger bore sizes or non-aluminium materials.

Questions about this item
Which 1 1/2 in NPSM shank coupling should I pick for a female-to-male swivel connection?
The 3LZ13 provides a female NPSM end and a male NPSM end on a single aluminium body, so one unit completes the swivel joint without extra adapters.
What does the 1 1/2 in NPSM rating mean when the coupling is pressurised?
It confirms both threads seal on 1 1/2 in NPSM pipe threads, letting the aluminium plug swivel under line pressure without leaking at the joint.
How does the NPSM thread standard limit the coupling in practice?
NPSM straight threads rely on a gasket or O-ring for sealing, so the joint holds pressure only when a compatible seal is installed in the female seat.
