American nlrbc1x11/4 Brass Insert Coupling 1 X 1-1/4 Inch Reducing

Product Description

The American nlrbc1x11/4 is a brass insert coupling designed for connecting and reducing between two different pipe sizes in plumbing and fluid handling systems. This fitting joins a 1 inch pipe to a 1-1/4 inch pipe, making it a reliable reducing coupling for systems where pipe diameters change along the run. Brass insert couplings are widely used by plumbers, pipefitters, and mechanical contractors because brass resists corrosion, handles moderate to high pressure, and forms a secure, leak-resistant joint with barbed or compression-style connections. The insert design allows the fitting to press into flexible tubing or pipe ends, creating a tight seal that holds under system pressure and temperature fluctuation. This type of coupling is common in residential and commercial plumbing, hydronic heating systems, irrigation lines, and industrial fluid transfer applications. The 1 inch by 1-1/4 inch sizing covers a common transition point found in supply lines, branch connections, and retrofit installations where two different pipe schedules or diameters meet. Brass construction provides durability and compatibility with copper, PEX, polyethylene, and other standard pipe materials. Plumbers and HVAC technicians keep insert couplings like this on hand for service calls, new construction rough-in, and repair work where a fast, dependable pipe connection is needed. The American nlrbc1x11/4 meets standard plumbing specifications and is identified by vendor product number NLRBC1X11/4, making it straightforward to order and restock. If you are working on a reducing connection in a potable water, heating, or general plumbing system, this brass insert coupling provides a proven, professional-grade solution.

• Brass construction resists corrosion and withstands system pressure and temperature changes
• Reducing insert coupling connects 1 inch pipe to 1-1/4 inch pipe for common diameter transitions
• Insert design creates a secure, leak-resistant joint compatible with PEX, polyethylene, and flexible tubing

Product Highlights

The American nlrbc1x11/4 brass insert coupling delivers a durable, corrosion-resistant reducing connection between 1 inch and 1-1/4 inch pipe sizes, suitable for plumbing, hydronic, and fluid transfer applications.
