Yes, applying too much Teflon tape to threaded pipe fittings is a frequent mistake that can cause significant problems during assembly and lead to joint failure. Wrapping the tape too many times creates excessive bulk and friction, making it extremely difficult or impossible to screw the male fitting into the female connector properly. Forcing an over-taped fitting places immense outward pressure on the receiving joint, frequently resulting in cracked PVC or metal fittings, stripped threads, or distorted seals that leak immediately. Sticking strictly to the recommended three to six tight wraps ensures a secure, leak-free connection without risking physical damage to your plumbing fixtures or spending unnecessary time struggling with stubborn installations.
