FAQ
Q1: When should I replace the water tank cap and gasket on my 768 sprayer?
A: Replace if you notice leakage from the tank opening during operation, the cap no longer tightens securely (stripped threads), or the gasket is cracked, hardened, or missing.
Q2: Can I replace only the gasket without replacing the cap?
A: Yes, in many cases the gasket can be replaced separately. However, purchasing the cap and gasket together ensures proper fit and sealing if the cap threads are also worn.
Q3: How do I determine the correct cap size for my 768 sprayer tank?
A: Measure the outer diameter of the tank neck threads (or inner diameter if female threads) using a caliper. Also note the thread pitch. Compare measurements to the replacement cap specification.
