Colar saddles are produced in diameters range 80 to 1600 mm of galvanized, aluminium and acid-resistant sheet at 15, 30, 45, 60 and 90 degrees angles.
They are recommended in the version with EPDM seals to ensure achieving "D" class leakage (airtightness) according to EN 12237 (SITAC certificate). In both versions there are several types of collar saddles:
Pressed pieces SP and SPL with 90° angle and lateral pipe diameter range 80-315 mm.
In case of non-standard lateral and pipe diameters and in versions where a lateral is bigger than a pipe diameter it is recommended to use SSC and SCCL T-pieces and symetric SS and SSL T-pieces.
In the case of angles different than 90 degrees SSCV and SSCVL collar saddles are offered, where angles may vary within 15 and 90 degrees.
