Eaton Dura-Seal™ is an integral benefit to Eaton’s 4S/6S spiral fittings* for both Aeroquip and Weatherhead products. Eaton took multiple series of fittings and combined and redesigned them to provide a streamlined spiral fitting portfolio – 4S/6S Series.In addition to the Dura-Seal o-ring, the fittings have either 4 or 6 identification rings on the outer socket to easily match with the corresponding hose to reduce guesswork.
Eaton Dura-Seal is an o-ring embedded into the nipple of the fitting creating a seal on the inside of the hose (in addition to the crimp). This best-in-class technology provides this fitting series with a Class 0 cool-down leakage rating, in accordance with SAE J1176 when used with Eaton hose, meaning there is no indication of moisture. This patent-pending innovation from Eaton eliminates leakage while also extending hose assembly life and reducing equipment downtime.
Many drips are left unidentified because there are no visual indications of the leak until performance has been affected. Leakage contributes to unnecessary energy consumption, money spent on top-off fluid and increased housekeeping costs.
Eaton 4S/6S spiral fittings have optimized the portfolio and the overall assembly process. Majority of the fittings have a reduced overall length, offering a lower profile to allow for easier hose assembly routing and installation. The formed back-up hex and captive slip over nut, decreases the risk of the fitting cracking during use. The elbow and hose nipple are now one-piece creating a non-brazed joint to reduce the chance of field issues. The rings etched into the fittings make it easy to match hoses to the correct fittings. Four rings on the socket refer to the 4-spiral hose and 6 rings refer to the 6-spiral hose; the hose I.D. is also marked on the fittings for quick identification, reducing the chance of assembly error. Together, these features reduce potential field warranty issues for both end-users and OEM users.
