Graco 223959 Ball Valve (Teflon) - Aftermarket Replacement | Bedford 29-1791

Control flow and isolate sections of your high-pressure fluid line with a compact shutoff built for finishing systems. This aftermarket valve replaces Graco 223959 and is referenced by Bedford as 29-1791, combining a 3/8 in × 1/4 in NPT body with PTFE sealing for reliable service.

Aftermarket Precision-Machined Industrial Duty

Why Choose This Ball Valve

  • Rated to 5000 psi (35 MPa) for high-pressure paint and coatings lines.
  • PTFE seals help resist common solvents and provide smooth actuation. :
  • Mixed-size ends (3/8" NPT × 1/4" NPT) simplify transitions between hose/manifold ports.

Service cue: Position the handle for clear visibility and avoid side-loading the stem to extend seal life.

Typical Compatibility

  • High-pressure fluid lines on Graco finishing and airless systems that specify this valve in their Illustrated Parts List.
  • Installations requiring an inline shutoff with 3/8 in NPT and 1/4 in NPT male ends (gun whips, manifolds, pump outlets).
  • Commonly supplied on industrial pump packages and accessories where isolation is needed.

Verify thread sizes and pressure ratings against your sprayer or pump manual before ordering.

What This Product Fits

  • Graco systems listing 223959 in the parts/installation sheets for high-pressure fluid lines.
  • Applications needing a compact 3/8" × 1/4" NPT shutoff valve with PTFE seals up to 5000 psi.
  • Bedford aftermarket cross-reference for Graco 223959: 29-1791.

For model-specific confirmation, match by the part number in your IPL or assembly diagram.

Installation Notes

  1. Relieve fluid pressure and lock out the sprayer/pump per the manual.
  2. Verify port sizes; prepare threads (NPT) with compatible sealant - avoid debris entering the line.
  3. Install the 3/8" side toward the larger manifold/hose and the 1/4" side toward the whip or accessory.
  4. Snug to seal; do not over-torque the stem area. Cycle the handle to confirm smooth operation.
  5. Pressurize at low setting and leak-check before returning to production.

Tip: Mount the handle where it won’t snag hoses; periodic cycling keeps the PTFE seats from sticking during long storage.

When to Rebuild / Replace

  • Handle binding or excessive torque to open/close at normal temperatures.
  • Weeping at the stem or ports after resealing the NPT threads.
  • Visible scoring, corrosion, or impact damage on the body or stem.
  • Inability to hold pressure when isolated during testing.
