Frequently Asked Commercial Door Gasket Measurement & Fit Questions

Q: What are the exact Dart-to-Dart and Outside-to-Outside dimensions for True 810778 / 810841?

The True 810778 / 810841 door gasket used on TDD-1 / TDD-2 / TDD-3 / TDD-4 Direct Draw Beer Dispensers measures 23-1/2" x 32-1/8" (TDD-2/3/4) | 22-3/4" x 31-1/2" (TDD-1) from Center-of-Dart to Center-of-Dart and 24-1/4" x 32-7/8" (TDD-2/3/4) | 23-1/2" x 32-1/4" (TDD-1) Outside-Edge to Outside-Edge (OD), using a 4-Sided Magnetic Push-In Wide Dart (True Black NSF PVC) retainer.

Q: Does True measure 810778 / 810841 gaskets Dart-to-Dart or Outside-to-Outside?

True specifies 810778 / 810841 by Dart-to-Dart (Center of Retaining Barb to Opposite Barb). True TDD-2, TDD-3, and TDD-4 multi-keg dispensers use OEM 810778 (23-1/2" x 32-1/8" Dart-to-Dart / 24-1/4" x 32-7/8" OD), whereas the compact single-barrel TDD-1 uses OEM 810841 (22-3/4" x 31-1/2" Dart-to-Dart / 23-1/2" x 32-1/4" OD). Always check both measurements in our caliper matrix before ordering.

Q: How do I install a replacement True 810778 / 810841 magnetic gasket so the corners seal flat?

Soak the new True 810778 / 810841 PVC gasket in warm water (110°F–120°F) for 10 minutes prior to installation to remove shipping memory creases. Snap all 4 corners into the door retainer track first, then press the center of each side rail inward without stretching the vinyl.
