Part number 730-172 is a precision-engineered Seal used across an extensive range of professional sprayer systems including Epic 690 GX, Advantage GPX 85, 690 GXC Airless Sprayer, PowrLiner 2850 GB_D_F, PowrLiner 1800M and 2800M, PowrLiner 2800, PowrLiner 3100, ProMark II, RentSpray 700, and SprayTech GPX 85 models. These professional units include airless sprayers and line striping systems for residential, commercial, industrial, and pavement marking applications. This seal creates leak-proof barriers between mating components, preventing fluid leakage and maintaining system pressure essential for reliable operation.
Manufactured from specially formulated materials resistant to solvents, water-based coatings, abrasive pigments, and the extreme pressures encountered in professional finishing applications, this seal is utilized in numerous critical locations throughout these sprayer systems. Common applications include sealing pump housings, fluid manifolds, valve assemblies, and pressure transducer connections. Its precise dimensions and material composition ensure proper compression and sealing force when installed in the designated gland across this diverse range of equipment platforms.
Seals are wear items that degrade over time due to chemical exposure, compression set, thermal cycling, and physical damage. A worn, hardened, or damaged seal will allow fluid to leak past, causing pressure loss, erratic operation, material waste, and potential component damage. Symptoms include external leaks at connections, difficulty maintaining pressure, and fluid seepage. Replacement with genuine 730-172 seal restores proper sealing integrity and ensures reliable operation across this extensive family of professional spray equipment.
| Fluid Containment | Prevents material leaks at component interfaces under pressure |
|---|---|
| Pressure Maintenance | Ensures system pressure integrity for consistent performance |
| Contamination Barrier | Blocks external debris from entering fluid systems |
| Visible Leakage | Fluid seeping from sealed joint during operation |
|---|---|
| Seal Degradation | Seal is flattened, cracked, hardened, or has pieces missing |
| Component Disassembly | Whenever a sealed component is opened for service |
| Preventive Maintenance | Replace during annual service or major system overhaul |
Part number 730-172 is specifically designed for a comprehensive range of professional sprayer systems including Epic 690 GX, Advantage GPX 85, 690 GXC Airless Sprayer, PowrLiner 2850 GB_D_F, PowrLiner 1800M and 2800M, PowrLiner 2800, PowrLiner 3100, ProMark II, RentSpray 700, and SprayTech GPX 85 models.

This seal is typically replaced during service of the component it seals. When servicing, these related parts are often addressed at the same time.
The part that the seal contacts. Inspect for burrs, scratches, or corrosion that could damage the new seal.
Light oil or silicone grease recommended for seal installation to prevent rolling and ensure proper seating.
Many applications have comprehensive seal kits that include this seal along with other related seals.
