Part Overview & Compatibility

Compatible Machines

A definitive model list for Graco 166211 Housing (also referenced as “Restrict-A-Flo Body”) is not published in Graco’s public parts listings. Fitment is model-specific—please verify your sprayer’s parts diagram for the housing/body that calls out part number 166211.

  • Check your sprayer’s exploded view: use the pump/manifold “Housing/Body” callout.
  • Match part number exactly (166211) before ordering.
  • If unsure, share your sprayer model & serial to confirm fitment.

How to identify & confirm fitment

  1. Locate your sprayer’s parts manual and open the pump/manifold section.
  2. Find the “Housing/Body” callout and confirm the part number reads 166211.
  3. Visually match port orientation, thread sizes, and mounting points.
  4. If your manual shows a superseded number, confirm interchangeability before purchase.

Installation notes

  • Replace associated O-rings/seals if the manual recommends it.
  • Tighten fasteners to the torque values specified by the OEM.
  • Pressure-test for leaks after reassembly.

Frequently Asked Questions

Fitment is confirmed only when your parts diagram specifies 166211 for the housing/body position. If your manual lists a different number, contact support to verify interchangeability before ordering.

This listing is for the housing/body only unless otherwise noted. Replace any O-rings, gaskets, or fasteners shown as separate line items in your manual.

Use the latest OEM number. If you see a different or newer callout, confirm the supersession path and compatibility before purchase to avoid returns.

You can, but it’s best practice to inspect and renew related seals, seats, and fasteners at the same time to prevent leaks and rework.
