Couplings connect two ends of a pipe or tubing. There are various types and sizes available depending on your application needs.

Flange couplings feature two ears connected by bores which line up along their respective axes, serving to attach fixing bolts for mounting on their respective coupling.

Camlock couplings require minimal maintenance, making them an excellent choice for applications requiring frequent coupling connection and disconnection. Installation is straightforward and they deliver long-term performance.

Cross Fittings

Cross fittings, or pipe cross connectors, are four-way fittings used to connect pipes in an “X” formation. With one inlet and three outlets each equipped with solvent-welded socket or female threaded ends for connection purposes, pipe crosses may create stress when temperatures change – therefore it should only be used where thermal expansion won’t be an issue.

Straight pipe crosses consist of three openings of equal size while reducing pipe crosses have two inlets and one outlet for fluid flow direction separation. Both options can add strength to framework while also helping direct fluids in different directions.

Elbow Fittings

Pipe elbows allow straight sections of pipe to be joined at angles, providing direction to liquid or gas flow while decreasing stress on piping systems and the potential for damage or fatigue failure.

There are different kinds of elbow fittings, including socket weld (SW) and threaded elbows. SW elbows feature trapezoidal sections and come in standard and full radius arc sizes.

Short radius bends force an abrupt change of direction, creating greater pressure loss than long-radius elbows.

Clamp Fittings

Clamp fittings, also known as tri-clover fittings, create leak-proof connections for pipes and hoses. Available in an assortment of sizes made from corrosion-resistant materials like stainless steel, these clamp fittings ensure secure connections for fluid transfer between systems.

Clips are used to securely fasten rubber couplings and clamp plastic pipe (such as poly pipe) onto barbed fittings, making them the ideal solution for systems requiring regular disassembly for maintenance or cleaning purposes. Installation is straightforward without requiring welding tools; making these clamps ideal.


Barbs are among the most beloved fish species among aquarium enthusiasts, making for easy care and entertainment value.

Hose barbs are measured according to their tubing ID, so when matching up an ideal hose or tube with its appropriate barb size, the tubing or hose should fit tightly without leaks or stretching over its barb connector. Additionally, its design can have an effect on how easily the connector can be assembled by hand.


Reducers are used to alter the diameter of pipes. There are two primary styles of reducers available – concentric and eccentric. Reducers are commonly employed in liquid and vapor piping systems.

Concentric reducers feature center lines with matching centerlines to maintain consistent top and bottom pipe levels, while eccentric reducers feature mis-matched centerlines, leading to flow disruption. They are often employed in horizontal gas piping at pump suction points; however they may also be found vertical fluid piping depending on their layout.

Tee Fittings

Pipe fittings connect pipes together, change directions or offset their length to accommodate obstacles such as electrical boxes. They come in an assortment of materials and sizes.

A tee joint connects two pipes at an acute 90-degree angle and is the most popular plumbing connector. You can also purchase equal tees where the branch pipe diameter matches that of the run pipe size, or reducers that have one end smaller than the other, along with nipple and plug fittings which seal off pipes completely.
