Optimal use and fit guidance

• Confirm compatibility by comparing the stem-top geometry and the hole diameter to the F2 plug’s profile—this model is designed for a specific stem-top match and may require a precise fit.
• Clean contact surfaces before installation to maximize seal integrity and extend the life of the plug.
• Lightly lubricate the perimeter with a compatible, non-reactive lubricant only if the equipment manual allows, to ease seating and removal.
