Ceramic seal with alumina-carbon rings and diameter 20mm.
The Ceramic Seal Roten 3 D.20mm is particularly suitable for clean water with temperatures between -30° +90°C.
Normally the seal is supplied with right spring, but on request is also available with left spring.
The use of alumina instead of steatite allows to enlarge the field of use of Roten 3 seal, making it suitable also for heavier uses (alumina is in fact resistant to corrosion, erosion and abrasion)
The field of application is enlarged with the inclusion of the two new Ø 38 and 40.
