Radium Engineering 6AN Male 6 AN Male 10 AN Female Y Adapter Fitting | Universal (14-0490)

Two 6AN branches into one 10AN trunk is textbook fluid math, and this Y does it in one piece.

The Radium Engineering 6AN / 6AN / 10AN Y Adapter Fitting merges two 6AN male legs into a single 10AN female leg, sizing the combined flow correctly instead of choking two lines into one of the same diameter. Catch can breather consolidation, dual vent merges, and twin-line returns all flow better through geometry designed for the job.

What You'll Feel

• Two circuits merged without the restriction of a same-size junction
• Smoother flow through Y geometry instead of hard tee corners
• Valve cover breather pairs consolidated into one full-size can inlet

Features

• Y adapter: 2x 6AN male legs merging to 1x 10AN female leg
• Machined anodized aluminum construction
• All fuel and oil types

The Details

The sizing is the point: two 6AN lines carry more combined area than one 6AN, so merging them into a 10AN trunk preserves flow where a same-size Y would bottleneck, the difference showing most in continuous-flow circuits like crankcase ventilation on engines with dual breather ports feeding one catch can. All three connections follow AN flare discipline, dry and clean, hand tight, then 1/4 to 1/2 turn, with two wrenches on the swivel end. Sold individually.
