An elbow connects two tubes at a fixed angle (usually 90°), a tee adds a third tube as a branch from a continuous run, and a cross joins four tubes meeting at a single point. Tees come in through and side-outlet versions depending on whether the main tube runs straight through. Selecting the right one depends on how many tubes meet and their orientation.

Pipe connectors are sized for standard steel tube of 42.4 mm (Size C) and 48.3 mm (Size D) outside diameter. The connector must match the tube's outside diameter for the grub screw to clamp securely. Mixing sizes is not possible, so confirm your tube OD before ordering fittings.

Pipe connectors clamp onto steel tube using an integral grub screw that is tightened with a hex/Allen key, so no welding or threading is required. The case-hardened screw bites into the tube wall to lock the joint in place. Fittings can be repositioned or removed by loosening the screw, making layouts easy to adjust.

Yes, galvanised pipe connectors are suitable for outdoor handrails, railings and barriers because the hot-dip galvanised malleable iron resists corrosion in wet and exposed conditions. This makes them appropriate for external staircases, balconies, ramps and industrial guardrails. For permanent outdoor use, pair them with galvanised steel tube of matching diameter.
