Torque vs. Sealant Balance
Properly tightening AN fittings involves more than just turning them until they feel snug. You need to find the right balance between torque and sealant application. Too much torque can damage the thread design or compromise material compatibility, leading to leaks or failure. Conversely, insufficient torque might cause seepage over time. Use a torque wrench that matches the specifications for your fittings, ensuring consistent, appropriate tightening. Pair this with a compatible sealant suited for your materials—aluminum, steel, or others—since different materials react differently to sealants and torque. Consider the thread design, as some fittings require specific torque levels to seat properly without damaging the threads. Achieving the right balance prevents seepage and maintains a reliable, long-lasting seal.
