Frequently Asked Questions
The 16T939 Hose Coupled is listed as a coupled system hose, not specifically a feed line hose. Some LineLazer units use different hoses for feed sections, so always confirm through your parts manual.
This hose is engineered for LineLazer pavement marking equipment. While it may connect to other systems with matching thread specifications, using it outside its intended family is not recommended for performance and safety reasons.
Replace the hose when signs of wear appear, such as reduced pressure, visible damage, leaks, cracks, or internal blockage. Regular inspections help prevent downtime on striping jobs.
