Brass Compression Elbow

Brass compression elbows in 15, 22 and 28 mm, turning a copper run through 90° without soldering. The 15 and 22 mm cover almost all domestic pipework; the 28 mm is for a main run or a heating flow feeding a whole floor. Tighten the nut firmly but do not overdo it — an over-compressed olive will weep rather than seal.
