Original Press Release:

Robust Port Stud(TM) from Parker Improves Assembly, Seal Reliability

COLUMBUS, Ohio-A newly designed adjustable port stud from Parker Hannifin Corporation's Tube Fittings Division provides easier field assembly while eliminating the potential for damage to the backup washer which can lead to leaks.

The patent-pending Robust Port Stud(TM) features a longer locknut that covers the threads and provides more gripping area for tightening the locknut. In the previous design, thread exposure below the locknut could lead to damage of the backup washer that pinches the O-ring, resulting in an O-ring extrusion gap with the potential to leak. Parker's new, beefier locknut eliminates the exposed threads, thereby preventing potential damage to the backup washer and O-ring.

Interchangeable with current SAE adjustable connectors, Robust Port Stud also boasts an easy, three-step assembly and requires no retrofitting of parts. The enhanced design is a running change in Parker's SAE product line, including Triple-Lok®, Seal-Lok(TM) and Ferulok®. The company also plans to apply the innovation to its metric and BSPP adjustable connectors.

Robust Port Stud's Advantages:
o Easy, three-step assembly-thread, align, and tighten
o More grip area for tightening the locknut
o Eliminates washer damage and potential leaks
o More reliable, leak-free connection
