Product Description

The Graco 117095 Compression Spring is a high-performance component engineered for precise mechanical response and consistent pressure within airless sprayer pumps. It ensures uniform material flow, reduces wear, and maintains smooth operation under heavy workloads.

• Cold-drawn stainless steel construction for corrosion resistance
• Precision wound coils with tight tolerance pitch control
• Cryogenic tempering for enhanced fatigue life
• Supports pressures up to 3,000 psi
• Direct-fit OEM replacement for reliable pump performance

Specifications

• Material: ASTM A313 17-7PH stainless steel wire
• Nominal cross-sectional diameter: 1.6 mm
• Tight tolerance coil pitch ±0.05 mm
• Shot-peened and cryogenically tempered for extended fatigue life
• Flat-ground end coils for stable seating

Installation & Maintenance

• Ensure axial alignment within pump manifold
• Apply thin PTFE-based lubricant on mating surfaces
• Inspect every 500 hours for wear, spring rate drift, or surface anomalies
• Replace if compressed height deviates more than 5% or spring rate exceeds tolerance
