Schedule 80 PVC Hex Nipples are essential fittings used to connect two female-threaded PVC components in a high-pressure piping system. The "HEX" (hexagonal) design refers to the six-sided middle section of the nipple, which allows for easy tightening using a wrench—making them especially useful in tight or awkward installation spaces where hand-tightening isn’t enough.

Key Functions of SCH80 HEX Nipples:

  1. Threaded Connection: Provides a secure male-to-male NPT threaded connection for joining valves, tanks, pumps, or fittings.
  2. High Pressure Resistance: Schedule 80 rating makes them suitable for systems under higher pressure than Schedule 40 fittings.
  3. Easy Installation & Removal: The hex design enables a strong and easy grip for wrenches, reducing risk of over-tightening or damage to threads.
  4. Chemical & Corrosion Resistance: Ideal for chemical applications where metal nipples would corrode.
  5. Reusable: Unlike glued slip fittings, threaded nipples can be unscrewed and reused if needed.

Why They Matter:

  • In industrial, commercial, or chemical systems, threaded HEX nipples allow safe, quick, and strong connections without solvent welding.
  • The Schedule 80 wall thickness ensures durability and performance in high-pressure and demanding environments, including irrigation, water treatment, and processing systems.
  • In maintenance operations, HEX nipples allow for easy disassembly and reassembly, saving time and reducing risk of system downtime.
