Do you need to seal rounded corners against wind, water, dust, or dirt? Bulb trim seals are industrial rubber products that provide sealing and insulation for machine doors, vehicle hatches, and equipment enclosures. They’re designed to seal rounded corners and have separate bulb and retainer sections. Each of these sections can use a different material and have a different durometer or hardness.
With bulb trim, the bulb section compresses to form a seal when the door, hatch, or enclosure is closed. The trim or retainer section attaches to a flange or substrate. To choose bulb trim for your application, you need to specify the bulb size, bend radius, and flange thickness. By choosing the right bulb size, you can avoid over-compression. The right bend radius and flange thickness help to avoid kinking and leakage. Continue reading Seal Rounded Corners by Starting with These Three Measurements
Bulb trim provides sealing and insulation for doors, hatches, and enclosures with rounded corners. These industrial rubber products have separate bulb and retainer sections, each of which can have a different durometer or hardness. The bulb forms a seal under low-to-medium closure force. The retainer or trim is pressed into place over a flange and may have an integral tongue or metal clips to promote attachment.
Elasto Proxy supplies a wide variety of bulb trim seals and can custom-fabricate finished gaskets that save time and money on your assembly line. In this article, you’ll learn how to choose the right bulb trim for your application. Whether you work in engineering, procurement, or production, compound selection and part dimensions are critical. Product features vary, too. Continue reading Bulb Trim Selection Tips

Bulb trim seals are industrial rubber products that are used to seal and insulate doors, hatches, and enclosures. They fit radiused corners and have separate bulb and retainer sections, each of which can have a different durometer (hardness) and use a different material. The bulb compresses to form a seal when the door, hatch, or enclosure is closed. The trim or retainer attaches to the flange or substrate.
Bulb trim seals keep out air, water, dust, and noise. They are used in doors with radiused corners and consist of a compressible bulb and a solid retainer section. When the door is closed, the bulb is compressed to create a seal between the door and the jam. The trim or solid retainer section installs over the edge of the door and combines a finished appearance with edge protection. Applications for bulb trim seals include mobile equipment and enclosures for electronics and machinery.
In this “How to” article from Elasto Proxy, you’ll learn how to install bulb trim seals so that they won’t over-compress or kink. First, you’ll learn about materials and measurements for the bulb section. You’ll then learn how to specify the trim section of your seal. Along the way, we’ll cover some calculations and best practices for ordering and installing the industrial rubber products that you need. Bulb trim seals are sold in coils, but they also come cut-to-length to help you speed installation. Continue reading How to Install Bulb Trim Seals
Bulb trim seals provide sealing and insulation for doors, hatches, and enclosures. These industrial rubber products have bulb and retainer sections that are made of different materials. The bulb section provides sealing and insulation under compressive force. The trim or retainer presses onto a flange or substrate. Each section of the seal also has a different durometer or hardness to support proper compression.
This technical article from Elasto Proxy is designed to help you choose the right bulb trim seals for your application. In addition to compound selection and part dimensions, product designers and technical buyers need to consider color, texture, internal supports, and exterior finishes. Your application may also require flame-resistant compounds or rubber that meets specific industry standards. Continue reading How to Choose Bulb Trim Seals

Bulb trim seals are sealing and insulation products with bulb and retainer sections. The bulb portion is often rounded or teardrop-shaped, but may resemble a half-moon or have a flat bottom. The retainer portion of the seal has a U-shape with an open end and two “legs”. The bulb provides sealing and insulation under compressive force, and the retainer or trim section presses onto the flange or substrate.
Each section of the seal (bulb and trim) are made of different materials. In turn, each material has a different durometer or hardness to support compression. For technical buyers and product designers, it’s important to choose the right materials and account for design factors such as bulb size, gap or edge thickness, and minimum bend radius. The following sections explain. Continue reading Bulb Trim Seals – Compound Selection and Technical Design
