What is a P-Shaped Rubber Seal?

P-shaped rubber seals (also referred to as “P-profile seals” or “P section seals”) are a simple way of saving energy and money by reducing heat loss and preventing drafts. P seal gaskets from Trim-Lok can be used in a variety of situations, particularly for sealing door frames and hinged windows.

Since our products are ozone and UV light resistant, Trim-Lok’s extruded rubber P seals can be used indoors, outdoors, and in extreme temperature and weather conditions. All our products are made in America using only the highest quality materials, meaning the P seals won’t crack or harden with time and can easily be cut to size.

Many believe that a seal’s hold increases with higher amounts of compression. However, Trim-Lok’s seals are designed to work best with a 25-40% compression of the bulb’s original height, with 25% being ideal. Compressing the seal more than this will negatively impact its lifespan and serviceability.

How do I use a P Seal Gasket?

As a proud manufacturer of extruded rubber seals, our selection of P section rubber seals are available in a variety of specially designed shapes, with several height and width variations available. P profile seals are ideal for hatch seals, door seals, and piping between the panels on cars and trucks.

Our extruded rubber P seals and P shaped door gaskets can be vulcanized to make frame or round endless gaskets and seals. Although we manufacture P seals in numerous sizes that are available off the shelf, custom sizes are available upon request.

Applying any Trim-Lok extruded P-profile rubber seal is easy:

  1. 1. Clean the application area with a solution of one-part isopropyl alcohol and one-part water. Only use a new, clean cloth to clean and dry the area, as a used cloth will introduce contaminants to the adhesive.
  2. 2. If your P Seal has adhesive, peel back a bit of the adhesive from the seal and begin applying. Only remove a bit of the adhesive backing at a time, so the adhesive remains covered as long as possible.
  3. 3. After the full seal is applied, go over it with your hands or a rubber roller to ensure even adhesion.

Our advanced manufacturing technology helps us fulfill orders of any size, and our strict quality checks ensure you’ll be receiving a high-quality product directly from Trim-Lok. While we may specialize in the design, construction, and distribution of rubber seals, including extruded rubber seals, it’s our flexible approach, dedication to quality, and exceptional customer service team that truly sets Trim-Lok apart from our competitors.
