Graco 178900 Sleeve Replacement for Bull 30:1 GH533 and King 63:1 Industrial Airless Sprayers Aftermarket by Bedford 57-1407
The Bedford 57-1407 Sleeve is a precision-machined aftermarket replacement for the Graco 178900 Sleeve used in heavy-duty airless pump lowers on Bull 30:1, GH533, and King 63:1 systems. As the critical wear surface for the piston and packing stack, this cylinder sleeve is honed to exact tolerances to maintain sealing integrity, reduce friction, and deliver stable output pressure. Built from hardened, corrosion-resistant steel and finished for low wear, it helps restore factory-level performance, extend packing life, and minimize downtime on demanding coating jobs-an ideal choice for contractors seeking OEM-level fit and reliability at aftermarket value.
Why Choose This Sleeve
- Direct replacement dimensions for the OEM Graco 178900 lower sleeve.
- Precision-honed bore improves sealing and reduces packing wear.
- Hardened steel resists scoring and corrosion in tough jobsite conditions.
- Stabilizes pump output for a consistent spray pattern across high-solids coatings.
Typical Compatibility
- Graco Bull 30:1 sprayers
- Graco GH533 systems
- Graco King 63:1 sprayers
Always verify against your sprayer’s parts list or lower assembly number before ordering.
