Factory Connection Information
Unlike many online listings, the factory reel is manufactured with 1/2" NPT female pipe connections. Included with the reel are two (2) factory reducing adapters that convert the connections to 3/8" NPT for compatibility with most commercial pressure washer hose assemblies.
This allows the reel to be used either:
- With the supplied 3/8" reducing bushings installed (most common pressure washer installations)
- Directly with 1/2" NPT plumbing by removing the supplied adapters for maximum water flow
Approximate Hose Capacity
Actual hose capacity depends upon the hose's outside diameter (OD). Thicker hoses will reduce the total amount of hose that fits on the reel.
