Product details

Description

The wrong fitting is the difference between an O-ring seal and a fuel leak you chase for weeks.

Every port on a Radium fuel rail, regulator, damper, or filter seals on an ORB boss, and matching it to your hose or hardware takes the right adapter. Radium Engineering 8AN ORB Fittings cover the spread: plugs, AN male conversions, metric and SAE adapters, barbs, and OEM FPR adapters, all machined and anodized for use with every fuel type. Pick the exact thread you need from the option list. Buy once, seal once.

What You'll Feel

  • Leak-free ORB connections that seal on an O-ring, not tape or paste
  • One listing to outfit an entire rail or regulator install
  • Clean adaptation from factory SAE and metric lines to AN plumbing
  • Reusable connections that come apart and go back together during service

Features

  • Male 8AN ORB (3/4-16) thread with O-ring seal on every fitting in this listing
  • Anodized aluminum construction, safe for all fuel types including E85
  • Adapter options: 1/8" NPT female, 8AN male, 10AN male, M12x1.0mm male, M12x1.25mm female, 8.5mm barb, 5/16" SAE male, 3/8" SAE male, and 8AN ORB port plug
  • OEM FPR adapters (20-0301, 20-0302, 20-0303) let a factory regulator or pulse damper bolt to an 8AN ORB rail port, in 11mm or 16mm bore with 39mm/M6 or 32mm/M5 spacing

The Details

ORB fittings seal with an O-ring compressed against the flat boss around the port, which is why they can be installed and removed repeatedly without damage, unlike tapered NPT threads. That makes them the right choice anywhere fuel plumbing gets serviced: rail ports, regulator inlets, filter caps, surge tank bulkheads. The FPR adapters in this listing deserve a note, since they solve a specific problem: reusing an OEM regulator or damper on an aftermarket 8AN ORB rail while letting it clock to the correct orientation. Match the bore and bolt spacing to your factory unit (the 16mm bore, 39mm spacing, M6 version fits the 4G63 Evo 8/9 regulator). For everything else, identify the thread on the far side of the connection, pick the matching option, lubricate the O-ring at install, and torque by hand plus a wrench snug. Fittings are sold individually.

Kit Includes

  • 1x Fitting per selected option

Applications
