166 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other grills, grill parts and burners, smokers and smoking gear, grill tools, outdoor griddles, outdoor kitchen appliances and grill covers we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The onlyfire propane adapter comes in at compact dimensions, measuring roughly 6.42 by 3.31 by 3.23 inches. At 13.7 lb, the listed weight is unusually high for a regulator or adapter of this size, which likely reflects packaging weight rather than the part itself. No material spec is listed, so buyers cannot verify the fitting material before purchase.
At $18.99 it is one of the more affordable options in this category. The 4.2-star average from 166 reviews is decent but below the top performers in this segment. That rating spread suggests most buyers get a working part, but a meaningful minority encounter fitment or sealing issues.
For occasional or backup use on a secondary propane burner or camp stove, this adapter can work fine. For a primary grill where you are cooking regularly, a part with a higher review volume and rating would give more consistent results.

Performance notes
This is a propane-rated adapter or regulator component. Dimensions are listed at 6.42 x 3.31 x 3.23 inches. No BTU rating, no flow rate, and no material specification are available. Because no material is published, buyers cannot confirm whether the body and fittings are brass or a lower-grade metal. Propane fittings made from lower-cost zinc alloys can be prone to cracking under repeated use or temperature cycling.
What buyers say
At 4.2 stars from 166 reviews, the onlyfire adapter gets a passing grade but trails the better-reviewed propane parts in this silo. The modest review count means one or two bad batches can pull the overall rating down noticeably. Buyers who leave positive feedback generally note that the part fits their setup and flows propane without issue. Negative reviews tend to mention leaks at the connection or difficulty getting a snug seal.

Frequently asked questions
What propane connection standard does this adapter support?
The listing indicates it is designed for propane LP use, but no specific connection standard such as QCC-1 or POL is explicitly detailed. Review the product listing images and description carefully before ordering to confirm the fitting matches your tank and grill.
Why is the listed weight 13.7 lb for such a small part?
The 13.7 lb figure very likely reflects shipping or packaging weight, not the actual weight of the adapter itself. Small propane fittings typically weigh a few ounces. Confirm dimensions and actual part weight with the seller before ordering if weight is a factor for your application.
