Our 90 Series remains our best-seller, year after year. Here’s why: Quality materials. Precision tolerances. Deliberate design.

The 90 Series was specifically engineered for heavy duty use in steel mills and municipal infrastructure plants. Today, it’s used across heavy industry. With a flared seal, the 90 Series v-ring creates a tremendous increase in the contact patch sealing area. Applying positive, continual pressure, the 90 Series v-ring forces seal adherence at all times.

Industrial swivel joint seal maintenance doesn't have to be a time and cost nightmare.

Seal swap OILCO's 857 Riser Swivel:
• In-field - within the swivel's footprint
• Using standard hand tools - no special equipment, no cranes
• With one technician - from your regular team
• In minutes, not hours - o-ring replacement in under 30 mins
• No disassembly required - loading arm stays in place

Bonus: Service life can exceed 30 years when operated and maintained under design parameters. We still get requests for seal replacement kits for first-gen units, many of which have been in service for 50 years.

Blog with details about the 857 and it's history linked in the comments!
