Product Overview
MAMAC Systems A-500-1-B-2 Thermowell
The MAMAC Systems A-500-1-B-2 is a 4-inch stainless steel thermowell that separates and protects a compatible temperature-sensor probe from the HVAC process medium. Its 0.255-inch bore is sized for MAMAC Systems’ standard 1/4-inch O.D. probe, while the 1/2-inch NPT external and 1/4-inch NPT internal connections identify the required piping and sensor-thread configuration.
Machined from one piece of metal and rated for pressure up to 3,000 PSIG, this model is intended for HVAC immersion temperature-sensing applications where its length, material, connections, and probe fit match the system requirements.

FAQs:
Q: What are the specifications of the MAMAC Systems A-500-1-B-2 thermowell?
A: The MAMAC Systems A-500-1-B-2 is a stainless steel thermowell with a 4-inch nominal length, 1/2-inch NPT external thread, 1/4-inch NPT internal thread, and 0.255-inch bore. It has a published overall dimension of 4.25 inches/108 mm, a 2.5-inch/64 mm “U” dimension, and a pressure rating up to 3,000 PSIG.
Q: Which temperature-sensor probe fits the MAMAC A-500-1-B-2?
A: The A-500-1-B-2 has a 0.255-inch bore designed for the manufacturer’s standard 1/4-inch O.D. temperature-sensor probe. Before ordering, confirm the sensor’s probe diameter, insertion length, and 1/4-inch NPT connection.
Q: What do the characters in part number A-500-1-B-2 mean?
A: In MAMAC Systems’ ordering structure, 1 identifies a nominal 4-inch/100 mm length, B identifies 1/2-inch NPT external and 1/4-inch NPT internal threads, and the final 2 identifies stainless steel construction.
Q: Is the A-500-1-B-2 interchangeable with other MAMAC A-500 thermowells?
A: A shared A-500 series name does not establish interchangeability. Match the complete part number or verify the thermowell’s nominal length, “U” dimension, material, probe diameter, external process thread, and internal sensor thread before selecting a replacement.
Q: Can MAMAC A-505 thermal compound be used with the A-500-1-B-2 thermowell?
A: MAMAC Systems offers A-505 thermal compound for the A-500 thermowell series to improve heat transfer and help prevent condensation inside the well. Confirm that the sensor and thermowell dimensions and connections match before selecting related accessories.
