Graco 24P192 Teflon O-Rings - Aftermarket Replacement | Bedford 55-3276

Durable PTFE O-rings sized for Graco displacement pumps and high-pressure sprayers. This aftermarket pack replaces OEM 24P192 and matches Bedford 55-3276, restoring leak control and prime retention in service rebuilds. Bedford and Graco documentation identify 24P192 as a standard O-ring used in Merkur pump lowers and related assemblies.

Aftermarket Precision-Machined Industrial Duty

Why Choose These PTFE O-Rings

  • PTFE (Teflon) construction resists swelling and common solvent exposure.
  • Sized to OEM geometry for quick installation and steady sealing.
  • Packed in sets for routine bench rebuilds and preventive maintenance.

Color cue: natural white PTFE O-rings; pair with OEM-specified lubricants for assembly.

Typical Compatibility

  • Graco Merkur® High Pressure Displacement Pumps (X48/X72 packages and related models) listing 24P192 in their parts tables.
  • Graco U-Cup Displacement Pump assemblies where 24P192 is specified as the lower-cylinder or seal O-ring.
  • General Graco high-pressure sprayers that use these pumps as part of the system package. Always confirm by IPL.

Check your pump IPL for the exact O-ring callout before ordering; 24P192 appears as a 10-pack for several seal positions in these pumps.

What This Product Fits

  • Merkur High Pressure sprayer packages using displacement pumps that list 24P192 (examples: X48, X72 configurations).
  • U-Cup Displacement Pump kits where the parts table specifies 24P192 for cylinder or inlet sealing.
  • Other Graco industrial sprayers built around the above pump families (verify by model IPL).

Bedford identifies 55-3276 as the aftermarket equivalent that replaces Graco 24P192.

Installation Notes

  1. Relieve pressure and isolate air/fluid per the pump manual.
  2. Disassemble the lower; document O-ring locations and orientations.
  3. Clean grooves and sealing faces; remove embedded debris.
  4. Install new PTFE rings carefully; avoid twisting or over-stretching.
  5. Prime at low pressure and verify for leaks/backflow before production.

Real Installation Tip: Warm PTFE in clean water (not hot) or use a tapered sleeve to ease over threads without nicking the seal.

When to Rebuild / Replace

  • Loss of prime or slow pressure build after startup.
  • Material weeping at the lower cylinder or inlet after cleaning.
  • Repeated packing adjustments with short service intervals.
  • Visible cuts/flat spots or chemical swelling on removed O-rings.
