The Graco H-40 Reactor is one of the most reliable hydraulic proportioners ever built. Designed for higher production spray foam applications, the H-40 combines hydraulic power, dependable operation and field-serviceable components that continue to keep thousands of machines working today.
Although no longer manufactured, many H-40 systems remain in daily service. SPF Depot stocks OEM and aftermarket replacement parts to help contractors maintain and repair these proven hydraulic reactors.
SPF Depot TSL Pump Rebuild Kit for Graco 246962
This SPF Depot exclusive rebuild kit contains the wear components commonly replaced during maintenance of Graco 246962, 246963, 246964 TSL pumps. Rebuilding the TSL pump helps maintain proper lubrication, reduce seal wear and extend proportioning pump life.
Used On
The Graco 117446 U-Cup Rod Seal is used in hydraulic pump assemblies found on Graco Reactor hydraulic proportioners. This seal helps maintain hydraulic pressure, prevents fluid bypass and supports proper pump operation during proportioning cycles.
Worn or damaged rod seals can result in hydraulic leakage, pressure loss, reduced pump performance and premature wear of other pump components.
Graco 117484 Thermocouple for Heater Block
The Graco 117484 Thermocouple is used to monitor heater block temperature on Graco Reactor proportioners. Accurate temperature feedback is critical for maintaining proper material temperature and system performance during spray foam and polyurea applications.
A failed thermocouple may cause temperature faults, inaccurate heater readings, heater shutdowns or difficulty maintaining set temperature.
