Description

Industrial Strength. Large Diameter Precision.

The 1" and Larger Schedule 80 PVC Nipples provide the structural integrity needed for high-capacity water lines. Designed for use in filter manifolds, pump stations, and main headers, these gray PVC fittings feature thicker walls than standard Schedule 40 options, offering superior resistance to pressure surges and physical impact.

Available in diameters from 1" up to 2" and lengths ranging from "Close" to 12" risers, these are essential irrigation fittings for professional installers. Whether you are plumbing a commercial greenhouse or a large agricultural field, these UV-resistant nipples ensure a secure, threaded connection. Don't forget to use Thread Sealant Tape on all male threads to prevent leaks.

Why Upgrade to Schedule 80?
  • High Pressure Handling: The extra wall thickness handles significantly higher PSI than Schedule 40, making them safer for mainlines near pumps.
  • Thread Stability: The robust material provides deeper, stronger threads that are less likely to cross-thread or deform under torque.
  • Chemical Resistance: Gray PVC is formulated to resist corrosion from acids, alkalis, and fertilizers often injected into irrigation systems.
  • Outdoor Durability: Contains UV inhibitors to protect against sun damage in exposed above-ground installations.

How to Install: A Step-by-Step Guide

Proper installation is critical for large diameter fittings.

Step 1: Prep Threads
Clean the threads of both the nipple and the receiving fitting. Apply Thread Sealant Tape to the male threads. For 1-1/2" and 2" sizes, verify if your system requires paste over tape (check local codes).

Step 2: Align
Carefully align the nipple with the female fitting. Large diameter PVC is easy to cross-thread if forced.

Step 3: Tighten
Hand tighten until snug. Use a large strap wrench or pipe wrench for the final turn. Caution: Do not overtighten, as the leverage from large wrenches can crack female fittings.

✔ Compatibility Check

Ensure size matching:

  • Match Diameters: A 1" Nipple only fits a 1" Female Pipe Thread (FPT) fitting.
  • Thread Type: Compatible with standard NPT/FPT threads found on valves, filters, and Sch 40/80 fittings.
  • Mixing Schedules: Safe to use with white Schedule 40 PVC fittings, though the system pressure rating will be limited by the weakest component.
