Quick-Connect Fittings are also called push-to-connect, push-fit, or SharkBite fittings. They allow for a quick and easy tubing connection with a locking collet design that grips the outer diameter (OD) of various tubing and pipe sizes. These fittings are designed for OD polyethylene and PEX tubing, as well as copper and PVC pipes.
What are quick-connect fittings used for?
- • Plumbing
- • Water purification
- • Reverse osmosis
- • Beverage dispensing
- • Appliance installation
- • Pneumatics
Types of Quick-Connect Fittings
ElbowsElbows are attached to pipes to change the direction of flow. Types of elbows include long-radius or 90° elbows and short-radius or 45° elbows. A 90° elbow is more common because it reverses the flow completely and keeps the tube from kinking.
TeesTees connect pipes of different sizes and merge or split the direction of fluid flow in three ways.
CouplingsCouplings join two end tubes together, often to add or extend a long run of tubing or pipe.
Bulkhead fittingsBulkhead fittings are used to create a connection through a wall. They’re inserted through a hole cut into the surface to join plumbing pipes and tubing to panels or tanks.
ConnectorsConnectors are straight fittings with a quick-connect end and a male-threaded end. Adapters are a type of connector with a female rather than a male-threaded end.
- • A ball valve is a type of shut-off valve that stops water flow
- • A needle valve regulates the flow of liquids
- • A check valve keeps water from flowing in the reverse direction
- • An angle stop adapter valve shuts off the water flowing to a faucet
Crosses and dividersDividers allow water to flow in separate directions. A cross coupler or connector is a four-way divider, named according to its number of inlets and outlets, similar to a tee.
Types of Quick-Connect Connections
Each quick-connect fitting has a different thread size and type of tube connection, like a union, reducer, push-in, stem, or barb.
UnionsUnions have the same size quick-connection on either side.
ReducersWhen the male and female quick-connect ends vary in size, the fitting is called a reducer. Reducers allow you to adjust pipe size depending on the flow rate a system requires.
StemsA stem has a short branch that plugs into a connector like a tube. A stem adapter has threads on one side to attach a union elbow or union tee.
BarbsBarbs are like stems but have a barbed end instead of a threaded end. A stem barb is a coupling that has a stem on one side and a barb connection on the other.
Connections vary in thread size and type.
