White polypropylene 4-inch Schedule 40 coupling, smooth cylindrical form, 80 psi rating

Orion

Orion 950120 Coupling Polypropylene 4 in Schedule 40 80 psi

SKU CH-DM4Z-CH3FZ

A 4-inch Schedule 40 polypropylene coupling rated for 80 psi maximum operating pressure

  • Polypropylene construction resists corrosion for long service life
  • Schedule 40 compatibility fits standard piping systems
  • 80 psi rating handles typical pressure demands
  • Operates from 0 to 160 degrees Fahrenheit across environments
  • Female no-hub ends allow direct solvent-weld connection

Orion 4 in Schedule 40 Coupling

This Orion 950120 coupling joins two 4 in Schedule 40 pipes in a straight line. The polypropylene body resists common chemicals found in drainage and industrial piping. It is built for installers who need a solvent-weld or mechanical joint without hubs.

80 psi rating and 160 °F limit

The fitting handles up to 80 psi at temperatures from 0 to 160 degrees Fahrenheit. Polypropylene construction keeps the joint light and quiet under flow, with no metal parts to corrode or transmit vibration. Pressure and temperature stay within the published range for Schedule 40 systems.

No-hub female ends simplify assembly

Each end is a 4 3/4 in female no-hub socket that slides over the pipe for solvent welding or gasket sealing. The 3 5/16 in overall length fits tight runs without extra fittings. No additional adapters or hub components are required for a complete joint.

Questions about this item

How do I install the Orion 950120 coupling on 4-inch Schedule 40 pipe, and what step is often missed?

The coupling has no-hub female ends for 4-inch Schedule 40 pipe with a 4 3/4-inch socket depth. Clean the pipe ends, apply compatible polypropylene solvent cement, and fully seat the pipe to the internal stop. The step often missed is allowing the joint to cure fully before pressurising.

What maintenance or replacement will the Orion 950120 coupling need over time?

Inspect the coupling periodically for stress cracking, discolouration, or leakage at the solvent-welded joints. Polypropylene can degrade under prolonged UV exposure or temperatures near the 160-degree Fahrenheit limit. Replace the fitting if any cracking, weeping, or loss of pressure integrity is observed.

What is the first limit reached when the Orion 950120 coupling operates continuously under pressure?

The coupling is rated for 80 psi maximum operating pressure. Sustained pressure at or above this rating is the primary limit. Elevated temperatures reduce pressure capacity, so the combined pressure-temperature limit will be reached before the 160-degree Fahrenheit temperature ceiling alone.
