Aquarium Plumbing Parts/Fittings

Aquariums using a sump, wet/dry filter, refugium or other external filtration system will require some type of plumbing. That’s why we carry just about every type of plumbing part you’ll ever need to make installation or replacement quick and easy.

Check out our huge selection of bulkhead fittings, elbows, barbs, strainers, tubing, check valves, ball valves and more.
Bulkheads and Strainers
Bulkheads
Bulkheads are available in different sizes and come standard or heavy-duty (from ½” up to 2”). Choose from threaded x slip, double-threaded and double-slip fittings.
Strainers
Bulkheads are available in different sizes and come standard or heavy-duty (from ½” up to 2”). Choose from threaded x slip, double-threaded and double-slip fittings.
Hosebarb/Insert Fittings and Vinyl Tubing
Flexible Vinyl Tubing
Vinyl tubing can be used in numerous applications although most commonly for plumbing a return line when PVC piping is not used. We carry ½” to 1” tubing in clear or black.
Flexible Kink-Free Tubing
Heavy-duty tubing reinforced on the outside to resist kinking and smooth on the inside to speed water flow. Tubing is flexible, yet will not crimp or collapse around curves. All sizes ½”-2” are designed to accommodate standard barbed fittings.
Hosebarb Fittings
Standard male and female barbed fittings, elbow barbed fittings and Y-barbed fittings are available in sizes from ½” up to 1” in size.
Hose Clamps
Available in both plastic (underwater or out-of-water applications) and metal (out-of-water applications only). Hose clamps should be used anywhere vinyl tubing is attached to a hosebarb fitting to ensure a tight fit.
Loc-Line Fittings and Return U-Tubes
1/2" Loc-Line Fittings
Loc-Line fittings allow you to customize the return plumbing inside your tank so you can direct and/or control your flow with nozzles, ball socket and numerous other fittings.
3/4" Loc-Line Fittings
Loc-Line fittings allow you to customize the return plumbing inside your tank so you can direct and/or control your flow with nozzles, ball socket and numerous other fittings.
Return U-Tubes
Easily attach to ½” to 1” vinyl tubing to make plumbing your return line an easy task. Available in two sizes.
Flow Accelerator
Increase water flow from your pump up to 400%. ¾” MPT fitting is durable ABS plastic. Available in ½”, ¾” and 1”.
Standard PVC Fittings
Bushings
Bushings increase or decrease plumbing sizes. Choose from an array of sizes available in Slip x Slip, Slip x FPT and Threaded x Threaded fittings.
Caps/Plugs
Caps and plugs seal outlets that aren’t being used or are placed at the end of PVC piping. Threaded, Slip and Insert fittings available.
Couplers and Adapters
Couplers attach two same-sized pieces of piping together. Use an adapter to transform a slip to a threaded fitting or vice-versa.
Elbows
Elbows are used to bend plumbing 90°, available in Slip, MPT and FPT in a wide range of combinations.
Flexible PVC Pipes
Bend and curve your plumbing around pumps, filters and other obstructions. Flexible PVC pipe retains its inner diameter and helps to avoid the need of elbow so that water flow is not impeded. Available in ½”, ¾”, 1” and 1 ½” sizes.
Tees
Split a single line into two. Available in Slip and FPT.
Unions
Unions allow you to detach plumbing without cutting any tubing. They are great to use before-and-after a pump so you can remove the pump without the disturbing the plumbing.
WYE
Less restrictive than Tee fittings, WYE fittings may be used as an alternative to achieve a higher flow rate through your tubing.
Valves
Ball Valves
Ball valves can help control or shut on/off water flow in your tubing. Available in standard or union; union ball valves combine a ball valve and a union fitting.
Check Valves
Check valves can prevent the back flow of water when a return pump is de-energized to prevent flooding.
Gate Valves
Similar to ball valves, gate valves can be used to control or stop flow. The handle lowers or raises a gate to control water flow.
Two Little Fishies Ball Valves with Hose Barbs
Barbed Aquatic Ball Valves for regulating water flow through standard hose used for devices such as canister filters, pump return lines, protein skimmers, calcium reactors, etc.
Others
JACO Fittings
Fittings primarily used for plumbing RO-type tubing.
