Bedford 20-3537 is Graco 237163 Kit aftermarket replacement

Graco 237163 Dura-Flo 900 (56:1 King L/T) Repair Kit — AfterMarket by Bedford Precision Parts

This kit is an AfterMarket by Bedford Precision Parts alternative to the Graco 237163. Sold as Bedford P/N 20-3537 and assembled in the USA, it’s engineered to refresh the Dura-Flo 900 lower with leather (QDF900-type) packings for reliable priming, tight sealing, and steady working pressure on demanding jobs.

Where it fits & how it’s used: Install on Graco Dura-Flo 900 lowers paired with 56:1 King air motors (L/T configuration). By renewing worn packings and seals in the lower, this kit helps reduce pulsation, stabilize patterns, and maintain film build for epoxies, urethanes, and other high-solids coatings in fabrication shops, shipyards, plants, and field maintenance. 

• Direct aftermarket replacement: Designed to match OEM form, fit, and function for a straightforward swap that minimizes downtime. 
• Performance focused: Leather packings and included seals restore prime/hold characteristics and help keep output stable across long shifts.
• Pro value: Bedford engineering and availability deliver dependable results at a cost-effective price point. 

Installation tips: De-pressurize and flush the sprayer, then follow your pump manual for disassembly, inspection, and torque specs. Lubricate new packings during reassembly; before returning to service, test the system’s pressure relief valve and perform a low-pressure leak check. 

Get job-ready results: A refreshed lower performs best with the right gun-side setup. Keep filters clean, size your airless spray gun tips to the coating, and equip operators with ergonomic paint sprayer guns to maintain pattern quality and reduce rework.
