1/2 inch Black Iron 45 Degree Street Elbow Female x Male

1/2 inch Black Malleable Iron 45° Street Elbow – For Directional Transitions in Threaded Systems

The 1/2 inch Black Malleable Iron 45° Street Elbow is engineered for joining piping at an angle where space constraints or directional flow requirements demand a precise, angled connection. With a female NPT thread on one end and a male NPT thread on the other, this fitting simplifies installation by eliminating the need for an additional nipple, making it especially useful in compact assemblies or when altering pipe routing without adding bulk.

Manufactured to ASME B16.3 standards and threaded in accordance with ANSI/ASME B1.20.1, this elbow is constructed from malleable iron and features a black oxide finish suitable for non-corrosive environments, including gas lines, compressed air, and hydronic heating systems. It is intended for use in low- to medium-pressure piping applications where reliability and mechanical strength are essential.

Key Features

• Material: Black malleable cast iron for structural integrity under pressure
• Size: 1/2 inch nominal pipe size
• Angle: 45 degrees for gradual directional change
• Connection: Female National Pipe Thread (FPT) x Male National Pipe Thread (MPT)
• Finish: Black oxide coating for general-purpose indoor applications
• Compliance: Manufactured in accordance with ASME B16.3; threads per ANSI/ASME B1.20.1

Installation and Use

This street elbow is commonly installed in gas distribution systems, heating applications, and air supply networks where angled transitions are required without additional couplings. For installation, ensure mating threads are clean and properly sealed using PTFE tape or thread sealant rated for the intended service. Hand-tighten initially, then apply torque with a wrench until secure, taking care not to overtighten and risk thread deformation.

Common Applications

• Natural gas and LP gas distribution lines
• Hydronic heating systems (hot water and steam)
• Low-pressure air compressor piping
• Dry fire protection systems (non-potable)

Note:

This fitting is not rated for potable water applications or corrosive environments unless protected by additional coatings or used in conjunction with galvanized or stainless alternatives.

The 1/2 inch Black Iron 45° Street Elbow is a dependable solution when transitioning pipe direction without introducing excessive fittings. Its durable construction and standardized threading make it a staple in mechanical and plumbing systems that prioritize longevity and code compliance.
