STZ Industries 2-1/2 in. FIP each X 2-1/2 in. D FIP Black Malleable Iron 90 Degree Elbow

Meet the STZ Industries 2-1/2 in. FIP x 2-1/2 in. FIP Black Malleable Iron 90 Degree Elbow — a purpose-built connector designed for dependable turns in 2-1/2 inch piping. Crafted from durable malleable iron with a hard-wearing black finish, this elbow provides a secure, leak-resistant transition between standard threaded fittings in residential and light commercial plumbing, heating, and irrigation layouts. Its lead-free construction supports safer potable-water applications, while the 90° angle helps you navigate tight spaces without sacrificing flow.

Key advantages

• Two FIP ends (2-1/2 in diameter) for straightforward integration with standard threaded pipe assemblies
• Robust malleable iron body with a durable black finish that resists impact and wear
• Precise 90-degree bend to simplify routing in cramped corners and mechanical rooms
• Lead-free construction for safer potable-water systems
• Maximum pressure rating up to 300
• Maximum temperature rating up to 150
• Bagged packaging for clean handling and secure storage

Ideal uses and scenarios

• Residential water distribution runs where a reliable 90° turn is needed without compromising flow
• Heating and radiant systems that require compact piping layouts in basements, crawl spaces, or utility closets
• Renovation projects that standardize on 2-1/2 in FIP connections for compatibility and ease of replacement

Installation tips

• Prepare threads by ensuring they are clean and free of debris before installation
• Use an appropriate thread sealant compatible with water systems (e.g., PTFE tape or pipe joint compound) and apply in the direction of threading
• Tighten by hand first, then snug with a wrench to avoid over-tightening and thread damage
• Position the elbow so there’s no undue tension or bending on connected pipes, preserving a smooth flow path
