ORIGINAL FURUKAWA QLW-A-3F-GR

Includes terminals and seals

The Component: Genuine Furukawa QLW-A-3F-GR. 3-Way female sealed automotive connector plug housing (Grey / Alternate Black variant).

Series Taxonomy: Furukawa QLW 250 Series. A heavy-duty, high-current Japanese automotive interconnect system engineered for rock-solid environmental protection and structural endurance across extreme powertrain vibration fields.

Terminal Interface: 3-pin single-row inline cavity configuration designed to house large-scale 6.3mm (250 series) flat female receptacle socket contacts.

Locking and Sealing Security: High-performance environmental sealing architecture providing dustproof and waterproof defense. Outfitted with an internal high-compression silicone perimeter gasket and a multi-port rear wire insulation mat seal block. Positive mating retention is handled by an integrated top mechanical thumb-latch locking arm that clicks firmly past the component header tab to absorb relentless high-frequency chassis movement.

Mating Complement: Connects wire-to-wire by mating directly onto the corresponding 3-way male inline coupling housing, or locks directly onto integrated module header frames under the matching QLW-A-3F-GR series footprint.

Common Applications: Extensively specified across global automotive, motorcycle, marine, and performance power sports networks. Most prominently deployed as the primary high-amperage factory repair pigtail for motorcycle voltage regulators, rectifier modules, alternator stator coils, and heavy-duty radiator engine cooling fan motors. Highly vulnerable to severe thermal fatigue, insulation tracking, and latch fracture due to the high continuous currents and extreme temperatures passing through stator and rectifier charging circuits.

Furukawa QLW-A-3F-GR QLW 250 Series 3-Way Sealed Female Rectifier and Cooling Fan Plug Housing

Eliminate charging system drops, drop engine operating temperatures back into safe parameters, and re-establish premium environmental isolation inside your wiring loom with the genuine Furukawa QLW-A-3F-GR 3-way female sealed connector housing. Meticulously manufactured to strict original equipment Tier-1 specifications by Furukawa, this heavy-duty 3-pin socket block is a foundational repair piece for handling intensive electrical loads. Designed with a spacious 3-position single-row layout optimized for 6.3mm flat female receptacle terminals, it safely manages continuous high-amperage current flows up to 34A without experiencing localized resistance spikes or thermal breakdown.

The QLW-A-3F-GR carrier block is injection-molded from a premium, chemically stable Polybutylene Terephthalate (PBT) compound, delivering outstanding structural rigidity, impact toughness, and complete immunity to warping across hostile engine and chassis zones. Equipped with an internal compression perimeter seal and a secure rear wire-entry seal layout, it builds an impenetrable barrier that keeps low-voltage and high-current terminal pathways completely dry and safe from road salt, moisture tracking, engine oil mist, and fuel grime. The heavy-duty top-mounted mechanical click latch ensures positive retention, locking the interface solidly together to combat aggressive engine harmonic fields. This authentic replacement component allows auto-electrical trade masters, motorcycle restorers, and fleet marine engineers to execute clean, zero-resistance factory pigtail rebuilds.
