Eaton™ Walterscheid™ WALRing Sets New Standard For Reliable Assembly Of Cutting-Ring Systems

BADEN-BADEN, Germany ... Diversified industrial manufacturer Eaton Corporation announced the launch of the Eaton™ Walterscheid™ WALRing, the new two-edge cutting-ring system with the time-tested WALFORMplus captive seals for simple and reliable assembly.

WALRing systems withstand operating pressures up to 800 bar (11,600 psi) with a 4:1 burst rating. It is offered in sizes ranging from six mm up to 42 mm and built to ISO 8434-1/DIN 2353 standards.

The WALRing assembly is composed of a DIN nut (which has an integrated two-edge cutting ring and additional support ring), the fitting body and the WALFORMplus captive seal. Like all cutting-ring systems, WALRing can be assembled with a standard wrench or by machine (controlled final assembly), which is a big advantage. Anotheradvantage of the WALRing system is that the possibility over-tightening is virtually eliminated. After one to one-and-a-half turns, the assembler will feel a noticeable increase in torque that clearly indicates the end of assembly. "These advantages distinguish WALRing from other competitive products," explained Jörg Altenrath, senior development engineer, Eaton Corporation. "Two cutting edges have been the tried and tested standard for decades because they absorb force uniformly, do not cut deeply into tube and reliably protect the WALRing against stripping-even in thin-walled tubes."
