Inserts and Hosebarbs for Aquarium Plumbing

A hose barb fitting is used as fish tank tubing connectors for "soft plumbing" an aquarium. For example, a hose barb can screw onto a submersible return pump and have flexible tubing attached to the other end. Be sure to use aquarium hose clamps to secure the tubing to the barb.

PVC fittings are listed according to PVC pipe sizes, not the actual measurement of the part. So, a 1 inch slip elbow does not measure 1 inch but fits onto 1 inch PVC pipe. PVC fittings are categorized by the types of connections they make:

MPT, or male pipe thread, has threads on the outside wall
FPT, or female pipe thread, has threads on the inside wall
A PVC slip fitting, or slip fit, has no threads and connects to PVC pipe
PVC insert fittings, or hose barb fittings, connect to aquarium tubing (not flex PVC pipe)
A reducer fitting reduces PVC size
