SAE aluminium tube fittings are 65% lighter than steel

Parker Hannifin is introducing a new line of SAE aluminum tube fittings that are approximately 65 per cent lighter than equivalent steel and stainless steel fittings; these are said to deliver customer value in terms of reduced transportation costs and more convenient hydraulic system conversion.

Specifying lightweight aluminum fittings from Parker can provide immediate fuel, freight and vehicle-transfer cost savings. The expense of converting a system from steel or stainless steel can also be minimised because no component redesign is necessary when performing a changeover - the fittings are manufactured to SAE J514 dimensions for 37-degree flare fittings and SAE J1453 dimensions for O-ring face seal fittings.

These new aluminum connectors are particularly suitable for applications where weight reduction and/or corrosion resistance are essential, such as in military, marine, mining, transportation and aerial lift trucks. The maximum working pressure rating for the fittings is approximately 50 per cent of that of equivalent steel fittings, while the temperature rating ranges from -40 to 204degC (-40 to 400degF), depending on the seal material.

Parker's aluminum O-ring Face Seal (ORFS) tube fittings feature patented Trap-Seal technology whereby a trapezoidal-shape seal provides superior retention in the O-ring face seal groove to prevent 'pop out' associated with round O-rings. This further reduces the risk of seal damage and leakage.

Another Parker-patented innovation, the Robust Port Stud, offers superior seal reliability of adjustable SAE aluminum connector port ends. With no exposed threads between the locknut and backup washer, the potential for washer damage - and resulting leaks - is eliminated.
