SPF Depot Replacement for 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.
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.

OEM Graco 247912 ISO inlet fluid tube for Reactor E-20 and E-XP1 proportioners. Non-insulated pump-to-heater tube. Cross reference 15B367.
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.
Graco 240523 Bearing Housing
The Graco 240523 Bearing Housing supports the proportioning pump drive assembly used on Graco E-Series Reactor proportioners. Proper bearing support is critical for maintaining pump alignment, smooth operation and long seal life.
Over time, bearing housings can wear from continuous operation, contamination, improper lubrication or bearing failure. Replacing worn components during a pump rebuild helps prevent premature seal wear and costly downtime.
Graco 246420 Pump Seal Kit
The Graco 246420 Pump Seal Kit is used to rebuild proportioning pumps found on Graco E-Series Reactor (E-20, E-30, E-XP1, E-XP2) proportioners. Replacing worn seals helps restore pump performance, maintain pressure balance and reduce material leakage during operation.
This kit is commonly used on both Gen 2 and Gen 3 E-Series Reactor systems and is one of the most frequently replaced wear components during routine pump maintenance.
