Product Description
The Graco 246978 Circulation Kit provides the components needed to recirculate polyurethane materials between a Graco Reactor proportioner and 55-gallon A-side and B-side supply drums. The kit uses separate return circuits to help maintain separation of the ISO (A) and resin (B) components.
Kit Includes:
- 2 return tube kits
- 2 H45010 nylon fluid hoses, 1/2" ID × 10 ft
- 2 reducing nipples, 1/2" × 1/4" NPT
- Required return-line connections for the Reactor fluid manifold
- Maximum fluid working pressure: 4,000 PSI (276 bar)
Important: A-side (ISO) and B-side (resin) components must remain separate to prevent cross-contamination.
