Premium Dual-Layer Foam Gasket – Dometic RTX Rooftop A/C Upgrade

Take your A/C install to the next level with our premium dual-layer foam gasket, precision-designed for Dometic RTX rooftop air conditioners. This upgraded gasket enhances both performance and peace of mind by improving your roof seal and reducing unwanted noise.

The top layer is composed of dense closed-cell foam that prevents air leaks and reinforces the seal. Beneath that, a softer open-cell layer helps absorb vibration and sound, contributing to quieter operation inside the cabin.

With 3M adhesive backing and a single-piece design, this gasket installs easily and conforms to roof contours for a flush, secure fit. For maximum waterproofing, we recommend applying a quality silicone sealant during installation.

Note: This premium gasket is not included with a standard Dometic RTX unit and must be purchased separately.

Approximate Dimensions (L × W × Thickness):
Outer Edge: 19.5" × 23.13" × 1.875"
Inner Cutout: 15.5" × 19" × 1.875"
*Small variances may occur.

  • Flexible Design: Thick 1-7/8" foam can be trimmed to match roof contours or support ribs.

Frequently Asked Questions

A: Yes, this gasket is compatible with both RTX 1000 and 2000 rooftop A/C units.

Q: Is the gasket included when I buy a Dometic RTX A/C unit?
A: No. This is a premium aftermarket gasket and must be purchased separately.

Q: What kind of sealant should I use?
A: We recommend using a quality silicone sealant to ensure a watertight seal, especially around roof ribs and seams.
