DUAL SPLIT FLANGE SWIVELS (8400 AND 8900 SERIES)
The OPW Engineered Systems ENDURA™ swivel line represents leading innovation in swivel technology. Specifically designed for the transfer of hazardous materials such as LPG, acids, solvents, petrochemicals and other toxic fluids, ENDURA™ sets the industry standard in swivel performance and cost-effective operation. Featuring heavy-duty flanged construction and available in a variety of materials.
Heavy-duty construction and unique design features result in long-life, hassle-free performance.
Smooth, Easy Operation
The sealed, one-piece deep-groove dual ball bearing assembly ensures smooth and easy rotation.
Improves Uptime Performance
The simple, three-piece design allows for the quickest and easiest disassembly and repair in the industry, which means less downtime, less labor, and less cost.
Lowest Overall Cost of Ownership
Heavy-duty construction ensures long-life reliability while the unique design features allow for cost-effective preventive maintenance servicing and the easiest, most cost effective seal and bearing replacement of any swivel. Optimized performance, downtime prevention, and reduced maintenance time and costs make this the best overall swivel value in the industry.
Full range of motion for ease of use. Deep-Groove Replaceable Dual Ball Bearing Technology – a precision-engineered, one-piece ball bearing assembly means there are no individual balls to deal with. If required, bearing replacement is quick and easy; simply replace the old bearing chamber with a new one. The ENDURA™ DSF 8900 Series features a 316 Stainless Steel replaceable dual ball bearing chamber.
Redundant Seal System
Incorporates a main seal, back-up seal, environmental seal and leak detection. If the main seal ever leaks due to normal wear, the back-up seal contains the fluid. Leakage is then channeled to a leak detection port in the side of the swivel to provide a visual indicator that service is required so the seals can be replaced. The environmental seal provides a third layer of protection, preventing liquid from entering the environment. Seal materials include Buna-N, Viton®, EPT, Kalrez®, Chemraz®, Silicone, and Food Grade.
Built-In Leak Detection
A visual indicator in the form of a leak detection port on the side of the swivel provides a quick and easy way to monitor seal leakage so preventive maintenance can be performed before a problem arises. The leak detection port can also serve as a purge port, permitting use of an inert blanket of gas to prevent product from escaping into the environment.
Available in 2", 3" and 4" sizes, and in a variety of construction materials, including carbon steel, stainless steel, Hastelloy®, Alloy20®, Monel® and other exotics. 500 PSI Pressure Rating

Custom made to fit our needs
Well built - heavy duty, but very easy to move. Custom made to fit our needs, and good customer service from John Edwards. Timing, and a quick turn around was key.
Westlake Longview Corporation
Exactly what I expected
All of my experiences with this purchase were positive. Travis McCraine was very responsive and ensured I had what I needed. The delivery was very quick and the product is exactly what I expected. The feature I liked most is the flexibility of this loading system. It's adaptive to many different truck heights, and the SafeRack team made this purchase very easy and the quick delivery cannot be beat.
Good design, easy to replace seal, and easy to weld with pipe without damaging bearings or seal.
RIght on Target
Customer service was prompt with quote. Sales was very thorough. Delivery was fastier than expected. Price was right on target.

Weyerhaeuser NR Company
They always come through for us
I have counted on SAFERACK several times to expedite shipment of these when we need one. Very responsive and helpful, keeping me informed all the way through the order and through shipment of product.
They have always come through for us. The safe rack is the piece of equipment we want and like in our plant. It makes the employees think "safety". It looks good, and they are the best safety device we have to load trailers.
Cabot Corporation (2153)
Ready for shipment
Saferack had material ready for shipment within 1 month or order placement. Other competitors offered 3 to 4 months. The product was easy to assemble, worked very well and came in different sizes. Saferack was the only company I wanted to provide me with the Gangway. I found that Saferack offered more quality items that I will purchase in the future.
Accounts Payable - Cartagena Refinery
addressed our safety concerns
Fast delivery, very responsive sales staff, and worked well addressing our safety concerns. The weight, dimensions, color and durability are all great benefits of this product. Not forgetting the overall reason to recommend this product, it improves safety.
City of Winnipeg
Exceeded our delivery we request
Heather Schaller, my inside salesperson, was very helpful in getting proposals to me, and getting order placed. We have a number of your gangways with safety cages, and our operators find them very user friendly. Construction is very good and the units look good in the plant. Saferack exceeded our delivery we request, receiving the product early. Thank you SafeRack and the SafeRack Team.
Rohm & Haas Chemicals LLC
Saved us time and money
The ease of installing our new universal safety gates, saved us time and money, which time is essential when dealing with safety. The univeral safety gate swings in both directions, and it can be mounted easily to almost anything. I really appreciate that we can inventory one gate for all services at our facility. I have had only positive feedback from refinery personnel about the gates and if I had to pick a negative it would have to be that I didn't know about the gates as soon as they came out.
Sinclair Wyoming Refining Company
Safest way to get on top of a truck

Watco Transloading, LLC
Very good impression!
John Nance was actually on site prior to place the order. Very good impression! Saferack is a major player in this market. With the ease of installation, good quality, and competitive prices, I would definitely buy again.
The International Group
The product is perfect
John Nance had great follow through during all steps: Sales To delivery. The gangway is strong, easy to install ( 1 part), and simple to use. The product is perfect.
IMTT - Quebec, Inc.
Would definitely purchase again
Very positive. Delivered within the estimated time frame. Easy installation, light weight and east to operation. I would definitely purchase again
CRS Proppants LLC
Delivered as scheduled. Able to meet more client needs with stock in hand is very handy. Easy product to handle, and a very important product for the oil and gas industry. Very satisfied.
Versatility / Completion / Light weight
Delivery was extremely fast. Mark Gardner was very courteous and helpful. With the ease of installation and cost savings of a complete unit, plus its versatility (left or right) completion (already painted) and lightweight make a YellowGate the simple choice. We will no longer have our safety gates fabricated. We will purchase these gates for all future installations.
The service is what makes the difference.
The delivery was as promised. Our previous provider fell short on service after the sale, and assistance in providing the correct product for the customer. I am very pleased with the service SafeRack provides. The salesman has been extremely helpful and has gone out of his way to assist in any way possible. Not to be negative, but the fall protection products are comparable, the service is what makes the difference.
