The Universal Bulb Seal (UWS 162-25) is a rubber-covered wire-core, push-on U-channel weatherseal engineered to protect and secure exterior edges and trim on a wide range of vehicles. It provides reliable sealing against water, dust, and wind while damping vibration and preventing metal-to-metal wear. Easy to install and highly durable, this seal is ideal for automotive restoration, repair, or routine maintenance where a strong, long-lasting edge seal is required.
Features:
- Rubber-covered wire core for strong grip and secure push-on attachment.
- U-channel design fits over edges to seal doors, trunks, hoods, glass channels, and trim.
- Reduces wind noise and vibration while preventing moisture intrusion and edge damage.
- Resistant to UV, ozone, and temperature cycling for long-term durability.
- Easy to cut and install — press-on fit with optional adhesive for permanent applications.
- Ideal for restoration, replacement, and general vehicle maintenance.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 15-30 minutes (per panel, depending on length)
Instructions:
- Measure the length of the edge or channel to be sealed and add a small allowance for trimming or joining.
- Clean the mounting surface thoroughly with isopropyl alcohol and a rag; remove rust, old adhesive, and dirt.
- Cut the bulb seal to length with sharp scissors, a utility knife, or by sawing the internal wire core; protect the rubber edge while cutting.
- Dry-fit the seal along the edge to confirm orientation and length. If joining two pieces, plan a butt or miter joint and trim accordingly.
- Apply a small amount of soapy water or rubber-safe lubricant to the U-channel to ease installation (avoid petroleum-based products).
- Press the seal firmly onto the edge, working along its length. Use a rubber mallet or wooden block to seat the wire core fully into the channel if needed.
- Trim any excess material and finish joints; for a more permanent or water-tight installation, apply an appropriate adhesive or seam sealer at the ends and joints.
- Inspect the installed seal for gaps, secure fit, and proper compression; adjust or re-seat as necessary.
