Class 125 PVC Bushings

Maxx Supply is proud to offer a wide selection of Class 125 bushings designed to reduce pipe diameter in various plumbing and industrial systems. These fittings are manufactured from durable, corrosion-resistant PVC and are available in a range of fitting sizes with threaded ends for simple assembly and tight sealing.

What is a bushing fitting?
A bushing fitting is used to reduce the inner diameter of a pipe fitting, allowing smaller-diameter pipe connections within a larger system. Maxx Supply's Class 125 bushings are rated for 125 PSI at 73°F and deliver a dependable, cost-effective alternative to metal options for both residential and commercial use.

Why choose Class 125 bushings?
These fittings are ideal for irrigation, water distribution, and large-scale plumbing systems — especially where pressure rating and corrosion resistance are critical. Class 125 bushings share many of the same thermal and pressure properties as Schedule 40 fittings, but at a more economical price point. Whether you're working with new installations or retrofitting existing systems, our bushings offer a fitting type that ensures compatibility and long-term performance.

Class 125 Bushing Installation Tips

  • Always inspect and clean threads before assembly
  • Apply PTFE tape or thread sealant to ensure leak-free performance
  • Hand-tighten fittings first, then use a wrench to snug (avoid overtightening to prevent cracks)
  • Ensure pipes are deburred and properly aligned before connection
  • Do not use Class 125 PVC bushings in systems where steam or extreme heat is present

Pro Tip: Use a torque wrench when working in tight or sensitive environments to avoid damaging the fitting.
