Graco 107550 Packing O-Ring

High-Pressure Packing O-Ring 107550: Advanced Sealing Solution for Airless Sprayers and Professional Coatings Systems

The Graco 107550 Packing O-Ring represents a critical sealing component engineered to maintain fluid integrity in high-pressure airless sprayer manifolds. Designed for professional coatings applications, this precision molded O-ring exhibits exceptional resistance across a wide temperature range and aggressive solvent environments. Manufactured from high-performance elastomers such as FKM (Viton) or PTFE-encapsulated compounds, the 107550 element delivers robust chemical compatibility and minimal compression set over extended duty cycles. Dimensional tolerances are held within ±0.025 mm for inner diameter and cross-sectional thickness, ensuring consistent contact pressure against mating surfaces. Integration with high-pressure filtration modules reduces particulate ingress and prolongs service intervals, while formulating with NSF-compliant materials supports regulatory adherence. Engineered to withstand pressures exceeding 3000 psi, the packing O-Ring contributes directly to pump efficiency and reliable fluid transfer in demanding industrial coating processes.

• Precision molded FKM material with optional PTFE encapsulation for aggressive fluids.
• Dimensional tolerance controlled to ±0.025 mm for consistent static seal engagement.
• Compliance with NSF and OSHA chemical exposure standards for industrial coatings.

Integration of the 107550 Packing O-Ring within Graco’s spray system modules enhances fluid control and leak resistance in advanced coating operations. When assembled as part of a precision manifold or pump inlet, this seal works in concert with vibration-dampening components and high-flow channels to reduce backflow and cavitation. Compatible with a variety of base materials and solvents, it ensures stable pressure profiles during cyclical load changes. Optimal surface finish on housing bores below 0.3 μm Ra promotes uniform compression and prevents micro-extrusion. Usage in graco sprayer accessories assemblies results in improved cycle life and consistent spray dynamics across a range of viscosities.

Incorporating the 107550 Packing O-Ring within high-pressure reciprocating pumps extends maintenance cycles by minimizing wear across dynamic seal interfaces. The optimized elastomeric profile reduces frictional heat build-up against polished steel pistons and valve springs, directly enhancing pump efficiency under continuous duty. Field tests demonstrate a 25% improvement in seal longevity compared to legacy nitrile designs, even when handling solvent-based coatings at elevated temperatures. Seamless integration into various graco pump parts assemblies allows technicians to retrofit existing systems without extensive modifications. Careful selection of hardness durometer and periodic inspection of gland surfaces further sustains performance in challenging environments, such as abrasive pigment slurries or high-viscosity polyurethanes.

Precise installation of the 107550 Packing O-Ring begins with thorough cleaning of gland bores and removal of debris to prevent extrusion under load. Technicians should apply minimal flange torque and a light film of compatible lubricant to avoid distortion during assembly. When used alongside a graco gun repair kit, these O-rings facilitate swift maintenance of tip guard seals and piston packings on airless sprayer guns. Integration with high-pressure filtration systems upstream in the fluid path prevents abrasive particles from compromising the seal interface. Routine inspection intervals of 500 operational hours allow for early detection of wear patterns, ensuring uninterrupted coating processes and minimal production downtime.

Laboratory evaluations of the 107550 O-Ring include dynamic life cycle testing under simulated pump stroke conditions exceeding one million cycles. Data indicates a leak rate below 0.001 cc/min at 150 bar, demonstrating an exceptional barrier for solvent-borne epoxies and high-solid polyurethanes. Additional dwell time pressure hold assessments confirm no visible creep when exposed to static loads for 72 hours at 200 bar pressure. Hardness variations between 70 and 90 Shore A are tested to optimize seal compression against each housing material and fluid viscosity profile. These performance metrics validate compatibility with high‐speed airless sprayer operation and professional coatings distribution, ensuring that formulation flow rates and spray patterns remain within specified tolerances throughout extended service intervals.

Manufacturers often specify alternative elastomeric compounds such as EPDM or HNBR for specialized chemical or temperature profiles when customizing the 107550 O-Ring. Custom tooling can adapt standard cross‐section dimensions to fit non‐standard pump housings or manifolds, supporting a wide spectrum of industrial spray systems. Quality assurance protocols include batch verification via digital calipers and micrometer gaging equipment, with every lot traceable to material certificates for full compliance. Regulatory considerations mandate California Proposition 65 labeling for certain materials, while RoHS conformity applies when electrical components are integrated. Tailored solutions leveraging advanced compound formulations further extend seal longevity in aggressive solvent environments and maintain optimal pump efficiency. The 107550 dual‐purpose design underscores Graco’s commitment to durable, high‐performance sealing systems across airless sprayer platforms.
