T-piece 90° for Ø 315mm duct and Ø 315mm spigot

The spiral pipe T-piece 90° lets you easily connect three separate spiral ducts. The duct has a diameter of 315 mm and is mounted with a 315mm perpendicular spigot.

Materials and specifications
Just like the spirotube in our range, the branch is produced to the highest standards using durable galvanised sendzimir galvanised steel (Z275). In the drawings and written specifications you will find all dimensions of the product. Our range also includes T-pieces with a 45° angle.

Airtightness class
All spiropipes and galvanised fittings comply with the strict airtightness class D (ATC 2), according to the European Standard EN12237. As a result, the airtightness of the connection pieces is excellent, leading to low pressure loss.

Easy installation thanks to rubber seal
Our spiro fittings, including these T-pieces, are fitted with a rubber sealing ring. This so-called safe-connection ensures an airtight connection without the need for other assembly materials.
