SKU CH-GCPF-1FCBT

ABS pipe adapter joining a 4-inch hub to a female NPT thread, Schedule 40 rated to 180 °F per ASTM D3965 cell class 32222

  • 4 in FNPT x Hub connects ABS pipe securely
  • Schedule 40 wall handles pressure in drainage systems
  • ASTM D3965 cell class 32222 confirms material quality
  • Operates from -40 °F to 180 °F for wide temperature range
  • Female adapter shape simplifies hub-to-thread transitions

4 in FNPT x Hub Adapter

The Value Brand adapter connects 4 inch ABS pipe to a female NPT thread in a hub configuration. It suits drainage and vent installations where a solvent-weld hub meets a threaded component. Plumbers and maintenance crews use it to transition between pipe systems without custom fabrication.

Thermals, noise and power

The ABS body handles continuous fluid temperatures from -40 to 180 degrees Fahrenheit without degradation. No moving parts or electrical elements are present, so the fitting adds no audible noise and draws no power during normal service.

Build quality and daily use

Schedule 40 wall thickness and cell class 32222 per ASTM D3965 give the hub enough rigidity for standard soil and waste pressure. The solvent-weld hub and FNPT thread allow direct assembly with common primer, cement and thread sealant, so installation follows routine workshop practice.

Questions about this item

How do you install the 4 in FNPT x Hub adapter, and what step do people often get wrong?

Clean the hub and pipe ends, apply ABS solvent cement to both surfaces, push fully into the hub, hold for the recommended set time, and avoid over-tightening the FNPT threads which can crack the Schedule 40 fitting.

What maintenance or replacement will this ABS adapter need later?

Inspect joints periodically for leaks or stress cracks; the ABS material rated to Cell Class 32222 per ASTM D3965 resists corrosion, so replacement is only needed if physical damage or joint failure occurs.

What limit appears first under sustained use at high temperature?

The maximum service temperature of 180 degrees F is the first limit; sustained exposure above this can soften the Schedule 40 ABS and compromise the hub or FNPT seal.
