novaSEAL ® OV Boiler rings


Properties
A special high-strength carrier fabric is coated
with natural rubber and rolled to endless rings.
The rubber components of the sealing ring lose
their elasticity at a temperature of 90°C.
After vulcanisation of the rubber the final
compression strength of the seal is reached.
Due to the setting behaviour the sealing ring
will also adapt to uneven sealing surfaces.
The rings are graphited on the outside.
 
Approval
Type-test approval acc. to TÜV TRD 401,class c.
 
Application
Hand-, head- and manhole seals for
boilers and tanks in round and oval shape.
