GJ3007 Equal Female Coupling – Straight Brass Fitting for Pipe Extension and Repair

The Coliter® GJ3007 Equal Female Coupling is a straight forged brass fitting featuring identical female ISO 228 (BSP) parallel threads on both ends, designed to connect two equal-diameter pipes in hot and cold water plumbing systems. Available in standard sizes such as G1/2"×G1/2", G3/4"×G3/4", and G1"×G1", it is commonly used for pipe extension, alignment, or repair without the need for soldering. Rated for PN16 (1.6 MPa) and suitable for operating temperatures from 0°C to 120°C, it delivers a secure, leak-free connection. Its durable, corrosion-resistant construction ensures reliable performance in both concealed walls and exposed installations.
