Tube fitting allows secure and repeatable assembly and reliable leak-free operations

ower management firm Eaton – now part of Danfoss Power Solutions (Sealing Technology, September 2021, page 2) – just lately expanded its product portfolio with the addition of the robust WALRINGplus delicate seal cutting ring system, optimised for thin-wall tubing.
Featuring Copy -edge cutting ring, with extra gentle sealing for each attainable leak paths, this tube fitting system allows straightforward, safe and repeatable meeting and reliable, leak-free operations.
It is designed to satisfy demanding requirements, involving hydraulic tube becoming in functions including use in agriculture, development, industrial autos, discrete manufacturing, rail transportation and other industries.
It is suitable for use with thin-walled tubes and, therefore, supports efficient weight and gasoline reduction of cellular equipment and shifting elements of stationary equipment.
Correct meeting is essential to tube fitting performance and WALRINGplus is designed to forestall extreme or insufficient tightening. A clear block-stop operate offers a tangible torque improve when the tip of an meeting is reached, so no torque or distance measurement is required.
In addition, a significantly lower drive is needed to drag the cutting ring over the tube – making meeting simpler, sooner and safer, whilst reducing the chance of damage to the delicate seal. The O-ring groove place also enables frequent reassembly, with out affecting efficiency.
To eliminate the chance of leaks that may create pricey damage and downtime, WALRINGplus additionally addresses their common root causes.
Soft sealing prevents leakages if: tubes or studs are slightly scratched, the fluid temperature fluctuates or the retention force is reduced. Problems attributable to low meeting torque also could be identified before the cutting ring is pulled from the tube – lowering the danger of a catastrophic failure in software.
The bespoke M-R7 machine additional reduces assembly time and the trouble required for WALRINGplus as nicely as the chance of leaks. By automating the process of cutting-ring meeting and tube-forming, this machine helps guarantee optimum system performance whilst additionally lowering the required torque and rotrotation.
Specifications of WALRINGplus: • steel cutting ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • high burst-pressure exceeding 4:1 safety issue; • working pressure up to 500 bar (L-series) and 800 bar (S-series); and • helps dry meeting with steel components.
