Russell 3-AN SAE Adapter — Zinc-Plated Steel, Pair for T56 Clutch Master/Slave

Russell 640281 is a straight zinc‑plated steel adapter that converts a master cylinder outlet to a 3‑AN male fitting for clutch master/slave systems.

This compact adapter is designed to join a T56 clutch master or slave cylinder to -3 AN braided line or hard plumbing. Made in the United States from zinc‑plated steel, it provides a corrosion‑resistant threaded transition where vehicle‑specific connections meet aftermarket AN fittings. The part ships as a pair and comes in vehicle‑specific fitment packaging sized for easy storage and installation.

How does this adapter simplify connecting a T56 clutch master or slave cylinder?

The adapter replaces the factory outlet with a standardized 3‑AN male thread so aftermarket lines and hoses attach cleanly. This removes the need for improvised fittings or cutting threads, making installation quicker and reducing leak points.

• Direct replacement for master cylinder outlets on compatible T56 clutch components.
• Creates a consistent -3 AN male thread interface for braided hose ends.
• Zinc plating improves corrosion resistance where road salts or moisture are present.

What materials and build quality should I expect from the Russell 640281?

This adapter is manufactured from steel with a zinc plated finish to balance strength and surface protection. Its construction is intended for mechanical robustness in hydraulic clutch systems without the softness of brass or the expense of stainless steel.

• Steel core provides durable thread engagement under torque.
• Zinc plating helps prevent surface rust and extends service life.
• Produced in the United States to control quality and thread tolerances.

How do I install the -3 AN SAE adapter when upgrading to braided clutch lines?

Installation is straightforward: remove the factory outlet fitting, thread the Russell adapter into the cylinder port, and torque to the manufacturer’s spec. Attach the -3 AN hose end to the adapter and bleed the system per vehicle instructions to eliminate air.

• Remove old fitting and clean threads before fitting the adapter.
• Hand‑start threads, then tighten to proper torque—avoid over‑tightening.
• Mount hose ends and perform full hydraulic bleeding to ensure clutch function.

Will this adapter fit my vehicle and what else comes in the package?

This is a vehicle‑specific fitment item; check compatibility with Russell or vehicle fitment guides before ordering. The product ships as a pair and is packaged compactly for convenient storage and transport.

• Package includes two adapters for master and slave applications or matching pairs.
• Compact box dimensions: 4.318 H x 12.953 L x 6.604 W centimetres.
