The 0528171 Nipple is a genuine OEM fitting component designed for PowrLiner, PowrTex, and PowrTwin series airless sprayers. This precision-machined nipple serves as a critical connection point in the fluid system, joining hoses, pumps, filters, and other components to create a continuous, leak-free path for paint and solvents under high pressure.
Manufactured from high-strength materials with precision-cut threads, this nipple is engineered to withstand the extreme pressures and chemical exposure common in airless sprayer applications. It maintains proper fluid flow characteristics while providing secure mechanical connections that resist vibration and pressure cycling. The nipple's design ensures proper engagement with mating components and prevents leaks at connection points.
Over time, nipples can become damaged from over-tightening, cross-threading, or corrosion from aggressive fluids. A damaged nipple can cause fluid leaks, air ingestion, pressure loss, and safety hazards. Replacing a worn or damaged nipple with this genuine part restores proper fluid system integrity and ensures reliable operation.

When replacing a nipple, it's good practice to inspect these related components, as they are often serviced at the same time.
Inspect hoses and mating couplings for wear, damage, or corrosion. Replace if necessary.
Check O-rings or gaskets at connection points for deterioration and replace as needed.
If the nipple is near a filter, inspect and clean or replace the filter element.
