The US bonded seal consist of a metallic ring with a molded, trapezoidal seal made of elastomer without a centring embossment. By tightening the screw, the elastic sealing lip gets pressed between the two flat surfaces. The compression of elastomer is limited to the strength of the metal ring.
As soon as pressure applies, the sealing effect is additionally increased. In addition to the standard elastomers, such as NBR, EPDM and FKM, different steel qualities are available such as standard steel (1.0330 galvanized) and stainless steel (1.4301).

Our Logistics – Your Service
Innovative, environmentally friendly and efficient
In addition to innovative techniques, our logistics has 2,870 sqm of process surface. We have the world's first AutoStore storage system on two levels. Both grits are connected to each other by means of special lifters. In total, up to 31,000 containers can be stored in a very confined space. Due to this subdivision, up to 240,000 storage areas can be managed most efficiently.
