29 For more information on OPW’s complete swivel line, refer to the OPW Engineered Systems Swivel Joints Catalog. Swivel Joints Endura™ 8000 Series Dual Split Flange ‘DSF’ • Tight Seals – O-Rings provide a tight seal without hindering swivel action • True Ball Bearing Race Alignment – Body and tail sections are locked together by a double row of ball bearings • Protected Bearing Chamber – Outer seal keeps out rain, dirt and other contaminants • Long-Life Bearings – Ball bearings are hardened, precision-ground steel – Stainless-steel swivels have stainless- steel bearings • Easy Lubrication – All OPW swivels pre-lubricated at the factory • No Field Adjustment Necessary – Balls are held in place by factory-installed plugs (never need adjusted) to maintain bearing performance Easy Maintenance • Simply unbolt sealing flanges to access seals • No ball bearings to remove Leak Detection Port • In the event of main seal leakage, fluid would be channeled to leak-detection port • Quick & easy way to monitor performance so that maintenance can be performed Purge Port • For critical applications, an inert gas can be injected at leak-detection/purge port • Inert gas pressure higher than product pressure to virtually eliminate risk of fugitive emission • Recommended for your extreme applications! Redundant Sealing • Incorporates a main seal, back-up seal, static product seal and environmental seal • If main product seal ever leaks due to normal wear, the back-up seal contains the fluid • Any main seal leakage would be channeled to leak-detection port • Environmental seal provides a third layer of protection Bearing Module • Deep groove replaceable dual & single race ball-bearing technology • Easy replacement or rebuild options • Ball removal not required to access main seals • Endura™ 8700-8900 series feature ALL stainless-steel construction Endura™DSF Swivels 3 2 4 1 5 6 1 Fabricated Steel and Stainless Steel Swivel Joints 3000 Series Swivel Joints • Best available swivel-joint technology • Designed specifically for chemical/ industrial loading arm use • Available in 2", 3" and 4" sizes; carbon steel and all stainless-steel versions in all styles • 500- psi pressure rating S Y S T E M C O M P O N E N T S NEW OPW 880 LUBRICANT • 100% synthetic • Formulated to reduce friction and wear • Will not melt, drip or carbonize • Compatible with all seal materials • Complies with FDA regulation 21 CFR 178.3570 • Requires only annual lubrication • Temp range: -40°F to 750°F (-40 °C to 400°C)
