Sigma 811024819 45 Degree Pipe Elbow 3 in Fnpt 150 Lb

Product Description

The SIGMA 811024819 is a FIG 3102 45-degree pipe elbow rated at 150 lb, designed to change flow direction at a 45-degree angle in threaded pipe systems. Constructed from malleable iron with a galvanized finish, this fitting resists corrosion and delivers the durability required in demanding plumbing, mechanical, and industrial piping installations. The 3-inch nominal size with female NPT (FNPT) ends on both sides ensures a secure, leak-resistant threaded connection. Domestically produced, it meets the expectations of plumbers and pipefitters working on systems where material quality and pressure rating matter.

This elbow is suited for residential and commercial plumbing, HVAC hydronic piping, fire protection systems, and general industrial piping where a 45-degree directional change is needed. The galvanized malleable iron construction makes it appropriate for water, air, and other compatible media in above-ground and moderate-environment applications. It is a standard threaded fitting installed by licensed plumbers and pipefitters on black or galvanized iron pipe systems.

Key Features

• 45-degree elbow angle for directional pipe routing
• 150 lb pressure-rated malleable iron construction
• Galvanized finish for corrosion resistance
• 3-inch nominal FNPT threaded ends for standard pipe connections
• Domestically produced to FIG 3102 specification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch nominal threaded iron pipe systems using FNPT connections at a 150 lb pressure rating.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Apply an approved pipe thread sealant or PTFE tape to all male threads before assembly and hand-tighten before applying wrench torque. Always depressurize and drain the system fully before removing or installing threaded fittings. Do not use this fitting in applications or with media outside its rated pressure and material compatibility.
