ClearFit PU Film CGM & Pump Overpatches

ClearFit is LINKFAR’s PU-film overpatch family for customers who prefer a transparent, lower-profile look. It is a different material route from the nylon, nonwoven and cotton textile ranges. A film may be designed to resist liquid water while allowing some moisture vapour to pass, but those are separate properties. Finished-patch results depend on the film, adhesive coating, edges, sensor shape and conditions of wear; “transparent” does not mean fully waterproof or irritation-free.

Choose the correct construction. ClearFit-P1 (08-2801) is the existing pump-oriented catalogue format for the devices listed below. The newer transparent P2 (08-2802, round) and P3 (08-2803, oval) are listed for Libre 3 and AiDEX X and use a fine-dot visual design. P1’s appearance or wear assumptions should not be carried over to P2/P3. Confirm the actual patch opening and the exact device instructions before selecting a SKU. Device names identify catalogue fit targets, not an affiliation with device manufacturers.

For OEM and distribution work, request the finished construction’s water-contact, moisture-vapour, edge-adhesion and skin-contact evidence for the intended use. Our P2/P3 development article explains the waterproof-versus-breathable design challenge; the CGM patch materials guide compares the four backing families, and the device-fit guide covers openings and fit.
