Frequently Asked Questions

Q: What size inflatable products is this air valve cap compatible with?

A: This air valve seal cap has a 22mm diameter, making it compatible with most standard inflatable mattresses, air beds, inflatable boats, canoes, rubber dinghies, and fishing boats that use a 22mm valve port. Always measure your existing valve before ordering to confirm compatibility.

Q: How does the one-way valve prevent air from leaking?

A: The one-way inflation mechanism allows air to flow in during inflation but blocks it from escaping once the valve is sealed. The screw-thread cap then locks over the valve opening, creating a secondary airtight seal to maintain pressure over time.

Q: Is this air valve cap easy to install?

A: Yes — the screw-thread design makes installation straightforward without any special tools. Simply align the valve with your inflatable's valve port and screw it securely into place for a firm, airtight fit.
