Pipe Nipple 5.5" L 3/4" x 5-1/2" NPT Alloy and similar items

Pipe Nipple 5.5" L 3/4" x 5-1/2" NPT Alloy Steel, Hot-Dip Galvanized - ProSource The ProSource 3/4x5-1/2 inch galvanized pipe nipple is a threaded alloy steel connector designed for reliable use in residential and light commercial plumbing, gas, or hydronic systems. Featuring standard NPT (National Pipe Taper) right-hand threads on both ends, it ensures a secure, leak-resistant seal when joined with compatible fittings. The hot-dip galvanized finish provides robust corrosion resistance for indoor and dry outdoor applications, while the solid alloy steel construction supports high-pressure performance and mechanical durability. Measuring 5.5 inches in overall length, this nipple is ideal for creating precise spacing between valves, fixtures, or pipe segments where rigid, non-flexible connections are required. Features - 3/4-inch NPT (National Pipe Taper) threaded ends on both sides - Made from high-strength alloy steel for pressure-rated applications - Hot-dip galvanized finish resists rust in dry and indoor environments - Overall length: 5-1/2 inches (5.5 in) for accurate pipe spacing - Right-hand threads standard for compatibility with most fittings - Suitable for water, air, and gas lines in non-corrosive systems - Rigid, non-flexible design maintains alignment under load - Meets standard dimensional tolerances for NPT pipe connections - Single-piece construction eliminates joints or failure points - Commonly used in plumbing repairs, HVAC, and fixture installations Specifications - Brand Name: ProSource - Part Number: 3/4X51/2G - Product Type: Pipe Nipple - Material: Alloy Steel - Finish: Hot-Dip Galvanized - Color: Steel (Galvanized) - Thread Type: NPT (National Pipe Taper) - Thread Direction: Right-Hand - Nominal Pipe Size: 3/4 inch - Overall Length: 5.5 inches - Item Weight: 0.48 lb (7.7 oz) - Country of Origin: China - UPC: 045734905146 - Global Trade Identification Number: 00045734905146 - Manufacturer: Worldwide Sourcing Product Application This galvanized pipe nipple is used by plumbers, HVAC technicians, and DIY homeowners to connect valves, faucets, regulators, or pipe sections in pressurized fluid systems such as potable water lines, irrigation manifolds, or gas appliance hookups. Typically installed in basements, utility rooms, or mechanical closets, it provides a fixed, rigid link where exact spacing is critical?such as between a shut-off valve and a water heater inlet. The NPT threads create a mechanical seal when tightened into female fittings, eliminating the need for additional couplings. Its galvanized coating offers adequate protection in dry indoor environments, though it is not recommended for continuous outdoor exposure or highly corrosive settings. As a fundamental component in threaded piping assemblies, it ensures structural integrity, leak-free operation, and long-term reliability when installed correctly with thread sealant.
