The AQUALINE PPN-38-40 is a Schedule 80 PVC threaded nipple designed for use in pressurized piping systems where corrosion resistance and chemical compatibility are required. Measuring 3/8 inch in diameter and 4 inches in length, this nipple serves as a short pipe extension or connector between fittings, valves, and equipment. Schedule 80 wall thickness provides greater pressure capacity than Schedule 40, making it suitable for demanding service conditions. Licensed plumbers, pool and spa technicians, and irrigation contractors commonly install this fitting in chemical feed lines, pool equipment plumbing, and industrial process piping.
This nipple is suited for residential and commercial plumbing applications where PVC is the specified material. Typical uses include pool and spa equipment connections, chemical handling systems, and general water service piping. The 3/8-inch size fits standard threaded fittings and valves commonly found in pool filtration equipment and low-flow plumbing branches. It is not intended for use with compressed air, flammable gases, or above the pressure-temperature limits of Schedule 80 PVC.
Designed as an OEM-style replacement or general-use fitting compatible with standard 3/8-inch NPT threaded Schedule 80 PVC piping systems.
Installation should be performed by a licensed plumber or qualified technician in accordance with applicable local plumbing codes and ASTM standards for PVC piping. Shut off and depressurize the system completely before removing or installing any threaded fittings. Use thread sealant or PTFE tape rated for PVC and the specific fluid being handled. Do not overtighten threaded PVC connections, as excessive torque can crack the fitting or the mating component.
