Door Seal Replacement – A Simple Step for Long-Term Performance

At Blentech, we design equipment that’s built to last—but like any high-performance system, a few wear parts need periodic replacement to keep things running smoothly. One of the most common? Door gaskets.

Found on equipment covers and discharge door assemblies, these FDA-approved seals play a critical role in maintaining sanitation, ensuring leak-free operation, and protecting your product integrity. Replacing them the right way—and choosing the right type—can make all the difference in uptime and long-term performance.

Customers upgrading from glue-in to press-in gaskets report better performance, fewer leaks, and less downtime.

Types of Gaskets: Glue-In vs. Press-In

Blentech uses press-in gaskets as the standard for most new equipment—they install quickly, require no adhesive or cure time, and offer a flush, sanitary fit that’s easy to clean and maintain. Glue-in gaskets are still used on legacy systems or where specific process needs apply.

Installation Tips for Success

Regardless of the type, here’s what you need to know for a clean, effective install:

1. Clean Thoroughly

• Remove old gasket and adhesive with a wire brush or wheel.
  • Kerosene can be used to soften stubborn adhesive.
• Wipe with acetone or lacquer thinner and let fully dry.

⚠️ Watch for “waves” forming as you press the gasket in; work them out so the seal sits evenly around the door. The incorrect installation photo, you can see variation in height—especially around corners—which is a clear sign of improper installation.

Tip: Removing the door makes installation easier (and it’s a great time to replace worn hinge pins).Consider upgrading to quick-release discharge door pins for faster maintenance. 

Sanitary Performance Matters

Gaskets aren’t just mechanical components—they’re part of your food safety system. Our press-in gasket design prevents product buildup, reduces contamination risk, and ensures a flush, leak-free seal. Customers upgrading from glue-in gaskets report better performance, fewer leaks, and less downtime.

Why It Matters

• Faster Turnaround: Press-in gaskets = no waiting = no lost shifts.
• Longer Life: Reduced mechanical stress = fewer replacements.
• Improved Food Safety: Sanitary, flush-mounted, product-safe materials.
  • Metal-detectable options available
• Lower Cost of Ownership: Fewer leaks, fewer failures, better ROI.
