The 22mm × 1" End Feed Bent Cylinder Union connects 22mm copper to a 1" BSP male boss with a swivel union nut, turning through 90° — soldered capillary joint on the copper end, threaded union on the other. The bend takes the pipework straight down or across from the boss without an extra elbow, and the union lets it be disconnected without unsoldering. Manufactured to BS EN 1254 and fits copper tube to BS EN 1057.

Also known as: bent cylinder union, angled cylinder connector, bent union connector, elbow cylinder union, tank union bent.
