GROCO Bronze Pipe Nipple - 1-1/2" NPT

The GROCO Bronze Pipe Nipple - 1-1/2" NPT (PN-1500) is a marine-grade plumbing and industrial connector designed for reliable fluid transfer in saltwater and freshwater systems. This short-length nipple serves as a critical coupling component in engine cooling loops, fuel systems, and seawater applications where corrosion resistance and durability are non-negotiable. Engineered for professionals who demand dependable performance in demanding marine and industrial environments, this fitting delivers the longevity required for both new installations and retrofit projects.

Constructed from C83600 bronze—a high-strength copper alloy specifically formulated to resist corrosion and dezincification—the GROCO nipple provides full flow passages with zero internal restrictions that compromise system pressure or efficiency. The cast-in wrench flat design simplifies both initial installation and future maintenance or removal without requiring pipe wrenches or specialized tools that could damage adjacent fittings. NPT (National Pipe Taper) connections on both ends ensure compatibility with standard marine plumbing infrastructure and allow for reliable, leak-free threaded joints when properly sealed with appropriate thread sealant.

This 1-1/2" nipple is ideal for boat builders, marine technicians, and industrial maintenance professionals working with through-hull fittings, seawater intake manifolds, and pressurized fluid distribution systems. The compact 2 x 2 x 3 inch footprint makes it suited for tight engine compartments and equipment cabins where space constraints limit fitting selection. For buyers seeking quality bronze pipe nipples for sale or searching bronze NPT specifications and marine plumbing solutions, the GROCO PN-1500 delivers proven reliability backed by marine-industry standards and real-world performance in harsh saltwater service.
