Static Seals
U-ring
Elastomeric gaskets to seal connecting elements and screw-in spigots. Applications with a mere elastomer or elastomer-metal bonding.
U-ring Type UZ
The UZ bonded seal consist of a metallic ring with a molded, trapezoidal seal made of elastomer and with a centering embossment for a safe automatic assembly.
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 galvanised) and stainless steel (1.4301).
