Primo Ceramic Grills Replacement Gasket

Primo Replacement Gasket (PG0177815)

Keep your Primo Oval XL-400 or Oval LG-300 kamado grill sealing tight and performing its best with this factory OEM replacement gasket. Designed for heat retention, proper smoke flow, and efficient fuel usage, this gasket is a small investment that can make a big difference.

Details & Specifications

• Made from high-quality, heat-resistant felt (or similar fibrous material) that can handle the extreme temperatures your ceramic grill reaches.

• Self-adhesive backing for easier installation.

• Kit replaces gasket material for the base, dome, and dome neck of the grill.

• Designed specifically to fit Primo Oval XL-400 and Oval LG-300 grills.

• Color: typically black (material finish), matching original gasket aesthetics.

• Weight: very light (around 0.2 lb).

What It Does

• Creates an airtight seal between the lid and base, helping to keep heat and smoke from escaping.

• Improves temperature stability — crucial for smoking, baking, or any long cook.

• Helps your grill reach and maintain higher temps sooner, with less charcoal.

• Extends the life of your grill by reducing excess heat stress on the ceramic body.

Why Replace the Gasket

Over time, the original gasket will wear — it can get compressed, fall apart, get sappy from grease, or simply lose its ability to seal properly. When that happens, you’ll notice things like:

• Heat not holding

• Smoke escaping from gaps

• Longer preheat times

• Less consistent cooking results

Replacing with PG0177815 restores the seal quality and helps your grill perform like new.

Installation Notes

• Best done when the grill is completely cool.

• Remove the old gasket material thoroughly. Clean the surface well (remove dust, grease, debris).

• Let the surface dry.

• Apply the new gasket: start at one point and gradually stick around, pressing to ensure good adhesion.

• Let the adhesive cure per instructions before using the grill at high temperature.

Good to Know

• Made in the USA.

• Replacement part — does not include the grill itself.

• Price typically in the $20-$30 range (varies by retailer).

This OEM Primo gasket (#PG0177815) is a cost-effective way to maintain your kamado’s efficiency and ensure your cooking remains consistent, whether you're smoking, grilling, or roasting.
