Radium Engineering O-Ring 5-Pack 8AN Viton | Universal (18-0043-08)

Eight-AN ORB carries the big flow in a Radium system, and its seals deserve a stocked shelf.

The Radium Engineering 8AN Viton O-Ring 5-Pack keeps five FKM (Viton) rings on hand for 8AN ORB (3/4"-16) fittings and plugs, the port size Radium rails, surge tanks, and hangers use for feed and crossover duty. Fuel-compatible through gasoline, E85, and oil service, these are the direct replacements for the seals every 8AN ORB service disturbs.

What You'll Feel

• Every 8AN ORB service finished with a fresh seal instead of a reused gamble
• Weeping rail and surge tank fittings actually fixed at the O-ring
• Five services covered by one small line item on the shelf

Features

• 5x FKM (Viton) O-rings for 8AN ORB (3/4"-16) fittings and plugs
• Compatible with all fuel types including E85, and oil systems
• Direct replacements for the seals on Radium 8AN ORB hardware

The Details

ORB joints seal entirely on the O-ring, making it the architecture's designated wear item: inspect on every removal, replace on any nick, flattening, or swelling, and always lubricate the new ring with O-ring lube, petroleum jelly, or oil before threading the fitting home. FKM's alcohol resistance is what keeps these seals honest through E85 blends that age lesser elastomers quickly. Rails with 8AN ORB end ports, surge tank feed fittings, and filter housings all draw from this pack over a build's life.
