Part 0277337 is a 30-foot flex hose assembly designed to deliver coating material between the pump and spray gun on compatible SprayTech airless sprayers. The flexible construction supports smooth material flow while allowing operator mobility and reduced hose strain during spraying.
| Part Number | 0277337 |
|---|---|
| Part Description | Flex Hose Assembly, 30 Ft |
| Function | Material transfer from pump to spray gun |
| Length | 30 Feet |
| Fits | SprayTech CS Series (8100, 9100, 9900 and 9960) |
The 0277337 Flex Hose Assembly (30 Ft) is used on SprayTech CS-series airless paint sprayers to transport coating material from the pump outlet to the spray gun. Its flexible design allows operators to move freely around the jobsite while maintaining consistent material delivery.
Over time, high pressure, abrasion, and repeated flexing can degrade hose integrity. A worn or damaged hose can restrict flow, cause pressure loss, or pose a safety risk. Replacing the flex hose assembly restores safe operation and reliable spray performance.
