Replace bellows, O-rings, and gaskets if you notice cracking, hardening, or leakage, or as preventive maintenance every 2–3 seasons depending on usage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the old gaskets and O-rings if they look okay?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Even if seals appear intact, they lose elasticity and sealing capability over time.
