Frequently Asked Questions
Q: What are the dimensions of the JT PT2036-2-7 copper washer?
A: The JT PT2036-2-7 copper washer measures 28 mm outer diameter (OD) by 1.5 mm thick. These dimensions are precision-specified for static hydraulic sealing in Jet PTW series pump assemblies.
Q: What material specification is the JT PT2036-2-7?
A: The JT PT2036-2-7 is manufactured from copper conforming to ASTM B152/B152M specification with a Brinell hardness range of 45 to 50. This material grade provides excellent thermal conductivity and static sealing performance in hydraulic circuits.
Q: Which pallet jack models use the JT PT2036-2-7?
A: The JT PT2036-2-7 copper washer is designed for Jet PTW series manual pallet jacks only. The 28 mm OD and 1.5 mm thickness are specific to Jet pump assembly configurations; do not substitute with washers from other manufacturers or models.
Q: What is the difference between the JT PT2036-2-7 and a standard steel washer?
A: Copper provides superior thermal conductivity and hydraulic sealing performance compared to steel. Copper does not create friction or spark under load, making it ideal for static sealing applications in high-pressure hydraulic systems. The JT PT2036-2-7 is designed specifically for this purpose in Jet pump assemblies.
Q: How do you identify if the JT PT2036-2-7 needs replacement?
A: Replace the JT PT2036-2-7 if you observe hydraulic fluid leakage near the pump assembly connection point, visible corrosion or pitting on the washer surface, or if the washer has become deformed or flattened. Copper washers are not reusable after removal; install a fresh part during reassembly.
