It is designed for reliability under typical residential and light commercial use, with a working pressure around 125 PSI and a maximum of 300 PSI. The coupling includes a rubber gasket and washer to minimize leaks and corrosion. Length is 4-1/8 inches with a 3/4 inch IPS connection, making it suitable for standard galvanized piping runs.
Eastman 4-3/8″ Long Pattern Compression Coupling
Brand: Eastman. This long-pattern coupling provides a heat-free solution for connecting galvanized pipe in repair or construction projects. With a 4-3/8 inch length and a 1″ IPS connection, it shares the same durable galvanized steel construction and includes a rubber gasket and washer to prevent leaks. Working pressure is 125 PSI, with a maximum of 300 PSI, offering robust performance for many plumbing applications.
Eastman 3-7/8″ Long Pattern Compression Coupling
Brand: Eastman. This 3-7/8 inch long coupling connects galvanized pipe without heat, suitable for repairs and new work. It features a 1/2 inch IPS connection, with a working pressure around 125 PSI and a maximum of 300 PSI. The heavy-duty galvanized steel body resists corrosion, and a rubber gasket plus washer help prevent leaks in typical water, gas, or light oil applications.
LDR 311 CCL-2 Galvanized Compression Coupling, 2-Inch
Brand: LDR Industries. This 2-inch galvanized compression coupling is designed for residential drinking water systems and is FM and UL certified. The galvanizing meets ASTM standards to ensure corrosion resistance, and the unit is 100% pressure tested. It is suitable for repairs or assemblies in standard galvanized piping networks where reliability and certification matter.
LDR 311 CCL-1 Galvanized Compression Coupling, 1-Inch
Brand: LDR Industries. This 1-inch galvanized compression coupling is FM and UL certified, 100% pressure-tested, and suitable for residential drinking water applications. The galvanizing meets ASTM standards, ensuring corrosion resistance in domestic piping. It provides a straightforward, leak-minimizing connection without the need for threading or heat during installation.
LDR 311 CCL-114 Galvanized Coupling, 1-1/4-Inch
Brand: LDR Industries. This 1-1/4-inch galvanized compression coupling from LDR is FM and UL certified, 100% pressure tested, and appropriate for residential drinking water systems. It features standard galvanization for corrosion resistance and provides a reliable, heat-free connection when joining galvanized piping in compact spaces or retrofit projects.
Buying Guide: Key Considerations For Galvanized Pipe Fittings
Material and finish: Galvanized steel fittings offer corrosion resistance and long life in potable water and general-use systems. Look for ASTM-compliant galvanizing and UL/FM certifications for reliability and safety in residential or commercial settings.
Connection size and type: Match the IPS (Iron Pipe Size) or specific inch size to your existing pipe. Long-pattern couplings can cover more surface area and may ease alignment during repair work, especially where pipe ends are not perfectly square.
Pressure ratings: Most residential galvanized fittings handle standard household pressures. Check the working pressure rating and maximum pressure to ensure compatibility with your system’s operating conditions.
Installation approach: Compression fittings provide heat-free connections that are convenient for repairs and retrofits. Ensure gaskets and washers are included or available, and confirm the correct tightening sequence to prevent leaks.
Certifications and testing: Prefer products with FM/UL certification and pre-tested assemblies. This adds assurance for leak resistance and safety in drinking water lines.
Availability and compatibility: Consider product availability from trusted brands (like Eastman and LDR) and ensure the chosen size and thread pattern align with your current pipe schedule and fittings family.
