Brass Nipple 1-1/2" x 14" Sch 40
This brass pipe nipple provides a 14-inch threaded connection for plumbing assemblies. The Schedule 40 wall thickness handles standard pressure requirements in water or gas lines. Male NPT threads on one end allow direct engagement with female fittings. The transparent brass finish resists corrosion in wet environments.
Installers extending a 1-1/2" line
Suitable for plumbers joining two female-threaded components across a fixed 14-inch span. The rigid length cannot be adjusted on site, so it does not suit installations requiring variable spacing. Buyers needing a different diameter, a shorter reach or a close nipple should select another fitting. Systems demanding a higher pressure class than Schedule 40 also require a different part.
14-inch fixed length
The overall dimension of 14 inches is the critical measure that determines whether this nipple fits the planned pipe run. No cutting or threading is possible after purchase without specialised equipment. Verify the centre-to-centre distance between the two mating fittings before ordering. An incorrect length will prevent assembly or stress the joint.

Questions about this item
How can I verify the 1-1/2" MNPT threads seal correctly after installing the 14" brass nipple?
Pressure-test the joint with water or air; a leak-free hold at working pressure confirms the Schedule 40 wall and tapered threads are functioning as intended.
What comes with the 4385012990 nipple and what must I supply separately?
The box contains only the 14" TBE brass nipple; you must provide pipe thread sealant or tape and any mating fittings required for your piping layout.
Which schedule rating should I select for a 1-1/2" brass nipple in a standard drainage run?
Choose the Schedule 40 version listed here; its wall thickness matches common residential and light-commercial drain, waste and vent requirements.
