T-Rohr PVC Fittings Aquarium Pool Verrohrung Rohr Muffe T-Stück 20mm

This fitting is designed for 20mm OD (outer diameter) rigid PVC pressure pipe. Always measure your pipe's outer diameter before ordering — nominal pipe sizes can vary by standard (DIN, BS, ASTM), so confirming the OD ensures a proper solvent-weld fit.

Yes. Rigid PVC is chemically inert in both freshwater and saltwater environments and does not leach harmful compounds under normal aquarium conditions. It is widely used for sump plumbing, return manifolds, and overflow boxes in reef and freshwater setups.

PVC has strong resistance to chlorinated water and common pool sanitizing chemicals at typical pool concentrations. It is a standard material for above-ground and in-ground pool circulation plumbing. Avoid prolonged exposure to concentrated chlorine solutions or UV radiation without UV-stabilized pipe.

This is a solvent-weld (glue-joint) fitting. Clean and dry both the pipe end and the socket, apply PVC primer if required by your local code, then apply PVC solvent cement to both surfaces and push the pipe firmly into the socket with a slight twist. Hold for 30 seconds and allow full cure time before pressurizing.

The choice is primarily aesthetic or organizational. White is the most common for general plumbing and blends with standard PVC pipe. Blue is useful for color-coding cold-water or freshwater circuits. Grey matches conduit-style pipework and is popular in workshop or industrial installations. All three colors share identical dimensions and performance characteristics.

Count the number of branch points in your pipe layout — each location where one pipe splits into two directions requires one T-fitting. For aquarium sumps, a typical two-return setup uses 2–4 tees. For pool loops, count each return jet branch. Ordering a pack of 5 or 10 is cost-effective for larger installations and provides spares for future repairs.

Rigid PVC fittings of this type are generally rated for cold-water pressure service. The exact pressure rating depends on the pipe schedule and the solvent-weld joint quality. For confirmed pressure ratings specific to your application, please contact us before ordering.
