Fittings that match the pipe and the equipment

Find the elbows, adaptors, bulkheads and connectors needed to complete or alter an Aquascape water circuit. Begin with the two components being joined and identify their actual connection types. Matching a nominal diameter is only the first step; socket dimensions and thread standards matter too.

Is two-inch metric pipe the same as two-inch Schedule 40?

Do not assume that it is. Nominal descriptions can refer to different actual dimensions. Check the specified fitting system and measurements.

More advice on choosing and installing

Know which part is doing the sealing

A solvent socket is bonded using the specified preparation and cement. A gasketed bulkhead seals around a penetration, and a hose tail works with suitable tubing and retention. Follow the fitting’s intended method rather than applying extra sealant to an incorrect connection.

Plan the joint before cutting

Dry-plan the route, support the adjoining pipework and leave access to serviceable joints. With a liner bulkhead, follow the exact cutting and assembly instructions; the surrounding pipe should not hang from the liner connection. Buy the required mating parts before making an irreversible hole.

Does a product photograph show everything included?

Exploded and installation pictures often show mating parts for context. The contents list identifies the connector or kit actually supplied.
