The FC-113 is a U-shaped channel seal extruded from EVA material, engineered for sealing glass edges within frame structures. Featuring a multi-barb inner design, this seal provides enhanced grip on glass surfaces without the need for adhesive. The clear transparent finish allows the seal to integrate visually with glass door and shower enclosure systems. Supplied in roll form with customizable length options, the FC-113 supports efficient sourcing for industrial applications and business operations.

This product is designed for use where glass panels meet aluminum or wooden frames, filling the gap between the two materials to create a water-resistant barrier. The U-shaped profile slides over the glass edge, and the barb structures on the inner channel walls engage with the glass surface to hold the seal securely in position. The EVA material offers flexibility and durability for repeated use in wet environments.

FC-113 Barb Design and Material Properties

Multi-Barb Retention System

The FC-113 features multiple barb ridges along the inner walls of its U-channel profile. These barbs are angled to allow the seal to slide onto glass easily during installation while resisting backward movement once seated. Each barb makes contact with the glass surface along the full length of the seal, distributing holding force evenly and preventing the seal from shifting out of position during normal use.

EVA Material Composition

Manufactured from EVA (ethylene-vinyl acetate), the FC-113 combines flexibility with dimensional stability. EVA material resists water absorption and maintains its physical properties under conditions commonly found in bathroom and shower environments. The clear formulation of the material ensures that the seal does not obstruct light passage or detract from the appearance of glass installations.

U-Channel Structural Design

The U-shaped cross-section of the FC-113 is engineered to fit over glass edges and sit within frame channels. The channel depth and width are proportioned to provide adequate glass coverage while maintaining a low-profile appearance. The outer walls of the U press against the frame material to create a seal along the installation length, reducing water passage and air infiltration at the glass-frame junction.

FC-113 Glass Seal Use Cases

Shower Door and Enclosure Sealing

The FC-113 is primarily used on shower doors and shower enclosures where glass panels are installed in aluminum or wooden frames. The barb design ensures the seal stays in place during door operation, maintaining consistent sealing performance over time. This makes it suitable for both residential and commercial bathroom installations.

Sliding Glass Door Systems

In sliding glass door applications, the FC-113 provides a cushioning seal between the glass panel edges and the frame channels. The barb retention system helps prevent the seal from dislodging during repeated door sliding motion, supporting long-term performance in high-traffic commercial facilities.

Display Cabinets and Showcases

The FC-113 can be applied to glass doors on display cabinets and retail showcases. The clear material preserves visibility of displayed items while the U-channel design provides a clean, finished edge appearance at the glass-frame interface.

Furniture and Cabinet Glass Doors

For furniture pieces and cabinetry with glass doors, the FC-113 serves as both a seal and a buffer. It reduces glass-to-frame contact noise and helps protect glass edges from chipping during door opening and closing.

FC-113 Installation Instructions

Step 1: Measurement and Cutting

Measure the length of glass edge where the seal will be installed. Cut the FC-113 seal to the required length using a sharp cutting tool. Ensure clean, straight cuts for proper end-to-end fit.

Step 2: Glass Preparation

Clean the glass edge surface to remove any dust, grease, or debris that could interfere with seal adhesion or barb engagement. Dry the surface thoroughly before installation.

Step 3: Seal Installation

Align the U-channel of the FC-113 with the glass edge and press the seal onto the glass along its entire length. Apply consistent pressure to ensure the barbs fully engage with the glass surface. The seal should sit evenly along the glass edge without twisting or buckling.

Step 4: Frame Assembly

Once the seal is properly seated on the glass, insert the glass and seal assembly into the frame channel. The outer walls of the U-channel will compress slightly against the frame material to form a seal along the installation length.

FAQ About FC-113

How does the barb design on FC-113 work?

The FC-113 features multiple angled barb ridges on the inner walls of its U-channel. These barbs allow the seal to slide onto the glass easily during installation but resist sliding back off. Each barb contacts the glass surface along the full length of the seal, distributing holding force evenly and keeping the seal in position during normal use.

What frame materials are compatible with FC-113?

The FC-113 is designed for use with both aluminum and wooden frame structures. The EVA material provides a compatible sealing surface against both metal and wood frame materials, filling the gap between the glass edge and the frame channel.

Is the FC-113 U seal suitable for shower environments?

Yes, the FC-113 is designed for shower door and enclosure applications. The EVA material resists water absorption and maintains its properties under typical bathroom humidity and temperature conditions. The barb retention system ensures the seal remains in place during regular shower door operation.

Can I cut the FC-113 seal to custom lengths?

Yes, the FC-113 is supplied in roll form and can be cut to any required length using standard cutting tools. This allows for precise sizing based on individual project dimensions, which supports efficient material usage and reduces waste for commercial procurement orders.
