Red and blue industrial polymer 3 inch hub by male NPT Schedule 40 adapter

Value Brand

Value Brand 3 in Hub x MNPT Adapter Schedule 40

SKU CH-8BK0-9DV6S

ABS Schedule 40 male adapter connects 3-inch hub to MNPT threads for drainage systems rated to 180 °F

  • Schedule 40 rating handles 180 °F service
  • Hub-to-MNPT adapter joins dissimilar pipe ends
  • Industrial-grade polymer resists corrosion and impact
  • Cell class 32222 per ASTM D3965 ensures material quality
  • Operates from -40 °F to 180 °F for wide temperature range

3 in Hub x MNPT Schedule 40 adapter

This ABS polymer adapter connects a 3 in hub to a male NPT thread in drainage, waste and vent systems. It meets ASTM D3965 cell class 32222 for industrial grade reliability. Plumbing contractors and maintenance teams use it to transition between solvent weld hub and threaded pipe.

Thermals noise and power draw

The fitting operates passively across a temperature range of -40 to 180 degrees F without fans, noise or electrical consumption. Schedule 40 wall thickness handles typical DWV pressure loads at these temperatures. No power supply or active cooling is required for normal installation.

Red blue color coding

The red and blue colour markings provide quick visual identification of the hub and thread ends during assembly. This reduces misconnection risk on sites with multiple fitting sizes. No software, tools or additional accessories are bundled with the adapter.

Questions about this item

How do I install the 3 in hub-to-MNPT adapter without cracking the Schedule 40 ABS fitting?

Apply ABS solvent cement to the hub socket only, insert the pipe fully with a quarter-turn, and hold for the manufacturer's recommended set time; the MNPT threads require thread sealant, not cement, which is the step most installers reverse.

What maintenance or replacement will the ABS adapter need over its service life?

Inspect the hub joint and MNPT threads annually for stress cracking or leaks; replace the fitting if the Schedule 40 wall shows crazing, deformation, or if the joint weeps after re-taping the male threads.

At what temperature does the Schedule 40 ABS adapter reach its rated limit during continuous hot-water service?

The cell class 32222 material per ASTM D3965 is rated to 180 degrees F; sustained exposure at or above that temperature will accelerate creep and joint failure before any pressure limit is reached.
