Weatherstrips: the small part that makes a big difference

At Gomantium we work with weatherstrips, edge trims, and profiles made from rubber and flexible PVC. They adapt to a wide range of applications and are available with a metal insert, adhesive backing, or standard fit for secure fastening and perfect fitment. We offer many shapes, sizes, and colors so you can find the best match for each use.

What is a weatherstrip?

A weatherstrip is a flexible rubber or PVC profile placed on edges, joints, or contact surfaces to seal, protect, and cushion.

• Edge trims and profiles to finish borders and prevent vibrations.
• With metal insert (clip) for a firm grip on edges.
• Adhesive-backed for sticking to smooth surfaces.
• Standard to snap into existing grooves or profiles.

Where are they used?

• Automotive: doors, trunk, hood, window frames, vans, camper vans/RVs, and motorcycle top cases.
• Industry: machinery enclosures, electrical cabinets, and inspection covers.
• DIY & home: doors and windows, storage lids, chests, furniture, and metal boxes.

Key benefits

• Sealing against water, air, and dust.
• Less noise and creaks thanks to vibration damping.
• Edge protection and a cleaner finish.
• Energy savings on household doors and windows.

How to choose your weatherstrip

1. Mounting area: edge, door joint, groove, or smooth surface?
2. Fastening system:
   • Metal insert → sheet-metal or plastic edges.
   • Adhesive → smooth surfaces without a groove.
   • Standard → to fit into an existing profile/groove.
3. Profile shape: U (with or without bulb), D, P, E sections or others, depending on the space to fill.
4. Dimensions: edge thickness, joint width, and bulb height. Tip: measure the opening and the compression space before buying.

Installation (summary)

Adhesive models

1. Clean and degrease the surface.
2. Dry-fit the path without stretching the strip.
3. Peel the liner and press down evenly.
4. Trim the excess and finish the joint.

Weatherstrips with metal insert (for edges)

1. Align the profile with the edge.
2. Press along the length so it grips the border.
3. Use a rubber mallet or roller for an even seat.
4. Make 45° miter cuts at corners for a clean finish.

Standard models (for grooves)

1. Position the profile in the guide or existing channel.
2. Snap it in with steady pressure until the perimeter is complete.

When it’s time to replace it

• Cracks, hardening, or a flattened bulb.
• Water/air ingress or new noises appearing.
• Vibrations or irregular closing of the door/lid.

Frequently asked questions

• Are they universal? Many models are, but it’s important to measure the edge and the joint.
• Can they be cut? Yes, with a utility knife or scissors. At corners, make 45° cuts for a better fit.
• Are they suitable for motorcycles? Perfect for top cases, fairings, and covers that vibrate or let in water/dust.
• Are colors available? Besides black, we offer several colors to blend in or contrast.
