Description
The GRACO 25C239 is a hose kit designed for use with two-component (2K) material dispensing systems, such as polysulfide sealant applications. It includes a base hose and multiple catalyst hoses, constructed for reliable delivery of base and catalyst materials in industrial mixing and dispensing equipment.
Key Features:
- Hose kit for 2K material dispensing
- Base: 3/4 in x 53 in (approx. 4.4 ft), Catalyst: 3 x 1/4 in x 60 in (5 ft each, but note: product listing may have a discrepancy; official GRACO documentation lists 3/4 in x 5 ft base and 5/8 in x 10 ft base in some kits, with 1/4 in x 5 ft catalyst hoses. The 25C239 kit is referenced as having a 3/4 in x 5 ft base, 5/8 in x 10 ft base, and 1/4 in x 5 ft catalyst hoses in three sections. The querys measurements may be a typo or misprint; please verify with GRACO for exact specs.)
- Compatible with GRACO 2K dispensing systems, such as those used for polysulfide sealants (e.g., HB Fuller PS-998R)
- Designed for reliable delivery of base and catalyst materials
- Supports efficient mixing and dispensing in industrial environments
- Ease of maintenance and replacement due to modular hose design
Applications:
Used in industrial settings for dispensing and mixing two-component materials, such as polysulfide sealants, in applications requiring precise material delivery and mixing.
Installation Notes:
- Using genuine GRACO hoses ensures compatibility, safety, and optimal performance with GRACO dispensing equipment.
- Ensure hoses are properly connected to the correct material sources (base and catalyst)
- Check for leaks and secure all fittings before operation
- Follow manufacturer guidelines for hose routing and support to prevent kinking or damage
- Regularly inspect hoses for wear and replace as needed
