Poly Pipe Nipple, 3/8” X Close

The 8M38 Poly Pipe Nipple (3/8" x Close) is a compact threaded connector designed for joining two female-threaded fittings in fluid transfer and plumbing systems. Manufactured from glass-reinforced polypropylene, this Schedule 80 fitting offers excellent durability, corrosion resistance, and reliable performance in demanding environments. Its close-length design provides a tight connection between components while maintaining strong pressure capability—because sometimes the best plumbing solution is simply a short, tough connector that does its job without complaint.
