Is the Steel Tube End with UNF GZ, Type 53213 compatible with hose types 3356 and 3090?

Yes. The Steel Tube End with UNF GZ, Type 53213 is explicitly designed for use with air conditioning hose types 3356 and 3090. Its external UNF threading and steel construction provide a secure, durable connection that is compatible with those hose types, ensuring reliable sealing, resistance to pressure and wear, and simplified installation and maintenance.

Does the Steel Tube End with UNF GZ, Type 53213 require specific torque settings for installation on hose types 3356 and 3090?

Based on the provided description, the Steel Tube End with UNF GZ, Type 53213 is engineered for durable, standardized connections with hose types 3356 and 3090. However, the description does not specify any required torque values for installation. For safe and reliable assembly, follow these general recommendations: - Use the manufacturer’s or system OEM’s specified torque values if available. - If no specification exists, tighten to a firm, leak‑free seal without over‑torquing: use a calibrated torque wrench and gradual increments while checking for proper engagement and sealing. - Avoid overtightening to prevent thread or seal damage; avoid undertightening to prevent leaks. - Where possible, consult hose/fitting datasheets, service manuals, or the supplier for exact torque specs and any installation notes (lubrication, sealant, or gasket requirements). If you need, I can help find or request the exact torque specification from the manufacturer or recommend typical torque ranges based on thread size and material.
