NPT Female Coupler - Straight

Two male NPT fittings and nothing to join them: the female coupler exists for exactly this.

The Finish Line Factory NPT Female Coupler - Straight handles fluid junctions for most automotive fuels, oils, and coolants, joining two male NPT fittings in matched sizes 1/8" NPT, 1/4" NPT, 3/8" NPT, 1/2" NPT, 3/4" NPT, 1" NPT through a straight female-female body. Precision made, and shaped for the systems that already committed to this thread standard.

Benefits

• The junction bolts together from parts on the shelf instead of a fabrication session
• Tapers bite progressively so each joint telegraphs when it's sealed
• Branch fittings aim independently, so routing stays sane
• One machined body replaces a cluster of improvised adapters

Features

• Female NPT both ends, sizes 1/8" NPT, 1/4" NPT, 3/8" NPT, 1/2" NPT, 3/4" NPT, 1" NPT
• Tapered thread sealing (sealant required)
• Compatible with most automotive fuels, oils, and coolants
• Straight coupler configuration joining two male NPT fittings
• Sold as a single fitting

The Details

Every port here is a tapered joint, so every connection gets sealant kept off the lead thread, and tapered threads sealing with proper sealant means final fitting orientation depends on where each taper stops. A female coupler is the mirror image of the male union: it swallows two male fittings, extending a run or joining a sender to a fitting stack. Back up the body with a wrench at every assembly step so torque on one port never disturbs another.
