Threaded Pipe Tee 3/4" SCH-40 FIPT 300-PSI Malleable Iron - ProSource 11A-3/4G The B K Mueller 11A-3/4G galvanized tee fitting is a heavy-duty, three-way plumbing connector engineered for reliable performance in residential and commercial water supply, irrigation, and compressed air systems. Crafted from malleable steel with a durable hot-dip galvanized finish, this fitting resists rust, corrosion, and mechanical stress ? ensuring long-term integrity even in damp or high-pressure environments. Its precise NPT (National Pipe Taper) threads provide a tight, leak-resistant seal when properly torqued with pipe dope or Teflon tape, making it ideal for both new installations and repairs. Designed to meet industry standards for pressure and durability, this single-piece tee maintains structural rigidity under continuous flow, eliminating the risk of cracking or deformation common in inferior cast fittings. Features - Made from high-grade malleable steel for superior strength and impact resistance - Hot-dip galvanized exterior finish for maximum corrosion protection - NPT threaded connections ensure secure, leak-free seals with standard piping - Three-way design enables efficient branching in water, gas, or air lines - Suitable for use in potable water, HVAC, irrigation, and industrial applications - Single-piece construction eliminates weak joints or weld failures - Meets ASME B16.3 specifications for malleable iron fittings - Compatible with standard 3/4-inch NPT pipes and fittings - No welding or special tools required ? hand-tightenable with wrench Specifications - Brand Name: B K Mueller - Model Name: B K Mueller 11A-3/4G - Part Number: 11A-3/4G - Product Type: Tee Fitting - Connector Type: Tee (3-way) - Thread Type: NPT (National Pipe Taper) - Size: 3/4 inch - Material: Malleable Steel - Finish: Galvanized - Color: Silver (Galvanized) - Item Weight: 8.02 oz (0.50 lb) - Product Dimensions: 18.5 x 12.59 x 9.44 inches - Package Quantity: 1 - Certification: Complies with ASME B16.3 - Manufacturer: B K Mueller - Country of Origin: United States - UPC: 045734101487 - Global Trade Identification Number: 00045734101487 Product Application The B K Mueller 11A-3/4G galvanized tee is the go-to choice for plumbers, contractors, and DIYers needing a rugged, code-compliant connection point in pressurized fluid systems. Whether installing a new sprinkler line, adding a faucet branch to a water main, or extending an air compressor circuit, this tee delivers consistent performance under constant pressure. Its thick-walled malleable steel body withstands thermal expansion, vibration, and minor impacts without cracking ? unlike brittle cast iron or thin-wall alternatives. Ideal for underground, exposed, or indoor use in garages, workshops, farms, and homes, it?s trusted by professionals who demand reliability over cost-cutting materials. Use with compatible black iron, galvanized, or copper piping (with proper adapters) to create lasting, maintenance-free runs. A proven component in legacy systems and modern builds alike ? built to last decades, not seasons.
