FAQ

Q1: How often should I replace the gasket?

A: Replace the gasket when you notice any leakage around the cup or if the seal appears flattened, cracked or swollen. Many users replace annually or whenever performance degrades.

Q2: Can I use this gasket with non-Graco brands?

A: While physically some gaskets may fit, we recommend using this gasket with Graco 1-quart cups only to guarantee OEM fit and performance.

Q3: Does this gasket affect spray quality?

A: Yes — a proper seal helps maintain pressure and prevents air or fluid leaks, which can negatively affect spray pattern, atomisation and finish quality.

Q4: Do I need lubricant or sealant when installing?

A: Typically no—these gaskets are designed to seal without additional sealant. Ensure the gasket and seating surface are clean, then install flatly.
