Nose Bridge Flex Coupler 90 - Dark Gray

This product is sold in pairs, each containing 2 pieces.
Hardness : 90

The color of this flex coupler is the same as OEM (Dark Gray) flex coupler.

The difference between 80 and 90 lies in the hardness of the material.

  • Flex coupler 80 is softer than 90, providing a comfortable fit.
  • Flex coupler 90 is harder than 80, offering a tighter fit.

We offer two colors at our store: black and dark gray. The only difference between them is the color. Please choose the color that suits your preference.

How to Replace:

Remove the nose bridge pin with a Pin Pusher (sold separately), and take out the old flex coupler, replacing it with a new one. Using the Pin Pusher, insert the nose bridge pin (ensure you change to a new pair of pins as well), and you will have a nice new pair of sunglasses.

If the X-Metal frame is used extensively, the nose bridge part may become loose due to damage to the flex coupler's rubber component. Revitalize your X-Metal by replacing the flex coupler and experience a renewed sensation.

It is made from silicone, graded for medical use, ensuring safety for your skin. We strive to deliver high-quality products for our customers.

This coupler is designed to be attached and functional across all generations of X-Metals.

X-Metal series nose bridges exhibit individual differences.

When performing repairs on the nose bridge, we kindly ask for your understanding of these variations.

About the Nose Bridge Pin:

Nose bridge pins can become loose if pushed in and out frequently. Therefore, we recommend changing the pin for a new one at the same time as replacing the flex coupler.
