Westward 22XP54 Coupling Pin Key 5/8 in

SKU CH-DKFN-T1NT0

Steel coupling pin key connects 5/8 in cables to compatible Westward drain cleaning machines

  • ColorTransparent
  • Fits Westward drain cleaners 22XP37, 22XP38, 22XP39
  • Connects 5/8 in cable to machine securely
  • Works with SP-HD25AC-7, SP-MD50, SP-MD50-1 models
  • Steel construction resists corrosion during heavy use
  • Designed specifically for coupling pin applications

Purpose and Compatibility

This Westward coupling pin key connects 5/8 in cables to compatible drain cleaning machines. It fits Westward models 22XP37, 22XP38, 22XP39, SP-HD25AC-7, SP-MD50 and SP-MD50-1. Buyers needing a different connector diameter or a key for non-Westward equipment cannot use this part.

Durability and Operation

The steel construction resists wear during repeated drain clearing jobs. No moving parts or lubrication points mean the key adds no audible noise or power draw to the machine. Installers who require a corrosion-resistant coating or a quick-release mechanism will not find those features here.

Included Scope

The package supplies only the coupling pin key itself. No additional cables, adapters or cleaning heads are bundled. Technicians expecting a complete accessory kit or a storage case must source those items separately.

Questions about this item

How is the 5/8 in coupling pin key installed onto the drain cleaning machine, and what step is often missed?

Align the key with the 5/8 in connector on the compatible cable, then secure it to the machine's drive end; the step often missed is verifying the pin seats fully in the coupling slot before tightening.

What maintenance or replacement will the steel coupling pin key need after repeated drain cleaning jobs?

Inspect the steel pin for wear, bending or corrosion after each use; replace it if the 5/8 in connector shows deformation or if the key no longer engages the SP-HD25AC-7, SP-MD50 or SP-MD50-1 cleaner couplings securely.

What limit appears first when the coupling pin key is used continuously on a Westward drain cleaning machine?

The 5/8 in steel pin can heat up and lose hardness under sustained high-torque operation, so the thermal limit of the material is reached before the mechanical connection fails.
