Product details

Description

Every 4AN ORB joint reseals on one small ring, and smart shops keep spares.

The Radium Engineering 4AN FKM O-Ring 5-Pack stocks the service drawer: five fuel-rated FKM O-rings sized for 4AN ORB (7/16"-20) fittings, the seals that every Radium 4AN ORB connection lives on and every disassembly should inspect.

What You'll Feel

  • Weeping ORB joints fixed on the spot instead of waiting on a single-ring order
  • Fresh seals at every service, replaced on principle rather than gambled on
  • Chemical confidence in fuel, E85, and oil duty from the FKM compound

Features

  • 5x FKM O-rings for 4AN ORB (7/16"-20) fittings
  • Fuel rated: gasoline, E85, and oil service
  • Direct service replacements for Radium 4AN ORB hardware

The Details

ORB O-rings age quietly, flattening under compression and swelling in fuel exposure, and the honest rule is inspection at every disassembly with replacement at any nick, flat, or doubt, since the ring costs cents and the leak costs weekends. Install discipline never changes: lubricate with O-ring lube, petroleum jelly, or oil before threading the fitting home, and never run an ORB ring dry. Five to a pack keeps the drawer stocked across seasons of service.

Kit Includes

  • 5x 4AN FKM O-rings (18-0043-04)

Applications

  • 4AN ORB (7/16"-20) fittings and ports
  • Fuel, E85, and oil service
