Spears 3/4 in Schedule 80 PVC Nipple

This Spears 1883-120 nipple is a 3/4 inch nominal Schedule 80 PVC pipe component measuring 12 inches overall length. It features a threaded connection on one end and is coloured gray for standard plumbing identification. The fitting handles a maximum pressure of 345 psi at 73 degrees Fahrenheit and a maximum temperature of 110 degrees Fahrenheit. It meets ASTM D1784 standards for material quality.

Suitable applications and limitations

This nipple suits installers needing a durable Schedule 80 PVC connection for cold-water pressure lines up to the rated limits. It is not for hot-water systems exceeding 110 degrees Fahrenheit or for applications requiring threaded ends on both sides. Buyers who need a different nominal pipe size or a longer overall length should look at other fittings.

Pressure and temperature rating

The decisive specification is the maximum working pressure of 345 psi at 73 degrees Fahrenheit combined with the 110 degrees Fahrenheit temperature ceiling. These two figures together determine whether the nipple matches the design conditions of the intended piping system.

Questions about this item

What pipe size and schedule must my existing piping match for this 1883-120 nipple to thread on correctly?

The nipple has a 3/4 in nominal pipe size and Schedule 80 wall thickness, so the mating pipe or fitting must share those same dimensions.

Can I join this gray PVC nipple to older metal pipe threads without damaging either side?

Use a compatible thread sealant and avoid over-tightening; the PVC material handles up to 345 psi at 73 °F but can crack if forced against rigid metal threads.

How do I confirm the joint is holding pressure after I install the 12 in nipple?

Pressurise the system to its working pressure — below the 345 psi rating — and inspect the threaded connection for any sign of leakage.
