Radium Engineering O-Ring 5-Pack 6AN Viton | Universal (18-0043-06)

The most common O-ring in a Radium system deserves its own five-pack.

Six-AN ORB is the workhorse port size across Radium rails, regulators, filters, and fittings, which makes its seal the one you replace most. The Radium Engineering 6AN Viton O-Ring 5-Pack stocks five FKM (Viton) rings sized for 6AN ORB (9/16"-18) fittings and plugs, fuel-compatible through gasoline, E85, and oil duty.

What You'll Feel

• Every 6AN ORB service finished with a fresh seal instead of a reused gamble
• Weeping fittings actually fixed, since the O-ring is almost always the answer
• Five services covered by one small line item

Features

• 5x FKM (Viton) O-rings for 6AN ORB (9/16"-18) fittings and plugs
• Compatible with all fuel types including E85, and oil systems
• Direct replacements for the seals on Radium 6AN ORB hardware

The Details

ORB joints seal entirely on the O-ring, making it the wear item of the architecture: 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 fuel resistance is what keeps these seals viable through alcohol blends that age lesser elastomers fast. Keep the pack with the AN wrenches and 6AN services stay one-trip jobs.
