Marshall Excelsior ME318P Pol Adapter Full Flow Review

Let’s Dive into Marshall Excelsior ME318P Pol Adapter Full Flow

The Marshall Excelsior ME318P Pol Adapter Full Flow is a seemingly simple component, but it is crucial for anyone utilizing propane for grills, camping stoves, or heaters. This adapter, crafted by Marshall Excelsior, facilitates a secure connection between your propane tank and regulator, ensuring a safe and efficient propane delivery system. For those unfamiliar, POL (Prest-O-Lite) fittings are common on propane tanks, and this adapter converts that connection to a standard 1/4″ MNPT (Male National Pipe Thread), a common size for regulators and appliances.

My journey to this adapter stemmed from a frustrating experience with an older, corroded fitting that was leaking propane. I needed a reliable replacement that could handle frequent use and varying weather conditions when outfitting a mobile cooking setup for a recent camping trip. The Marshall Excelsior ME318P Pol Adapter Full Flow stood out due to its advertised durability and full flow design, which promised optimal propane delivery.

Upon receiving the adapter, I was immediately impressed by the solid construction and heft of the brass. The threads were clean and precisely cut, suggesting a high level of manufacturing quality. It felt significantly more robust than the lightweight aluminum adapters I had used previously.

While I didn’t have the exact same adapter to compare, I did have two other POL adapters on hand: a basic, low-flow adapter, and a high-flow adapter that included an excess flow valve. I chose the Marshall Excelsior ME318P Pol Adapter Full Flow for its advertised durability and simple, uninhibited propane flow. My goal was reliable operation without the potential flow restriction of an excess flow valve.

My first impression was positive – the adapter felt like a quality piece of hardware that would provide years of reliable service. I was particularly pleased with the 7/8 inch nut size, which felt substantial and easy to grip for tightening, unlike some smaller, more fiddly alternatives.

Real-World Testing: Putting Marshall Excelsior ME318P Pol Adapter Full Flow to the Test

First Use Experience

I tested the Marshall Excelsior ME318P Pol Adapter Full Flow during a week-long camping trip in the mountains, where nighttime temperatures dipped into the low 40s. I used it to connect a 20-lb propane tank to a portable propane grill and a camping stove. The adapter performed flawlessly, providing a consistent propane flow to both appliances.

The conditions were relatively dry, but there was some moisture in the air during the evenings. Even with the dampness, the adapter remained easy to grip and tighten without any slippage. The connection remained leak-free throughout the entire trip, providing peace of mind and a consistent cooking experience.

Using the adapter was straightforward. I simply threaded it onto the propane tank’s POL valve and then connected the regulator to the 1/4″ MNPT outlet. No sealant was needed, as the threads sealed perfectly with just a bit of hand tightening. After the initial setup, I didn’t need to adjust or re-tighten the adapter at all during the trip.

There were no issues or surprises during the first use. The adapter did exactly what it was supposed to do: provide a secure and reliable connection. The full flow design seemed to deliver ample propane to both appliances without any noticeable pressure drop.

Extended Use & Reliability

After several months of use, the Marshall Excelsior ME318P Pol Adapter Full Flow continues to perform reliably. It has been subjected to multiple camping trips, backyard barbecues, and even some use in my workshop to power a small propane heater. It has remained leak-free and shows no signs of corrosion or wear.

The adapter shows no signs of wear and tear other than some minor surface scratches. The brass has held up well to repeated tightening and loosening, and the threads are still in excellent condition. The nut also remains easy to grip, even with dirty or greasy hands.

Maintenance is virtually non-existent. I simply wipe the adapter clean with a damp cloth after each use to remove any dirt or grime. I also periodically inspect the threads for any damage, but so far, they remain in perfect condition.

Compared to previous adapters I’ve used, the Marshall Excelsior ME318P Pol Adapter Full Flow significantly outperforms them in terms of durability and reliability. The solid brass construction and precise machining make it a superior product that should last for years to come. I have not experienced any of the problems (leaks, corroded threads, difficult tightening) that I have encountered with cheaper adapters.

Breaking Down the Features of Marshall Excelsior ME318P Pol Adapter Full Flow

Specifications

• Connection: Male Hard Nose POL x 1/4 inch MNPT. This configuration is standard for connecting a propane tank to a regulator or appliance with a 1/4″ NPT fitting.
• Nut Size: 7/8 inch. The 7/8″ nut provides ample surface area for gripping and tightening, even with gloves or wet hands.
• Material: Brass. Brass construction provides excellent corrosion resistance and durability, ensuring a long lifespan.
• Flow: Full Flow. The full flow design allows for maximum propane delivery without restriction, ensuring consistent performance from your appliances.
• UL Listed: Not UL Listed. This adapter does not include an excess flow valve and is not UL listed.

These specifications matter because they directly impact the adapter’s performance, durability, and ease of use. The brass construction ensures longevity, the full flow design maximizes propane delivery, and the 7/8″ nut makes tightening and loosening easy and secure. The absence of a UL Listing means that it lacks the excess flow safety feature, so proper leak testing after connection is even more critical.

Performance & Functionality

The Marshall Excelsior ME318P Pol Adapter Full Flow excels at its primary function: providing a secure and reliable connection between a propane tank and a regulator or appliance. The full flow design ensures consistent propane delivery, which is essential for maintaining optimal performance from grills, stoves, and heaters.

The adapter’s strengths lie in its durability, ease of use, and reliable performance. However, the lack of an excess flow valve is a potential weakness. For applications prioritizing maximum safety, a POL adapter with an excess flow valve might be a better choice.

The Marshall Excelsior ME318P Pol Adapter Full Flow meets my expectations for a durable and reliable propane adapter. It performs consistently and shows no signs of wear or degradation after months of use. The solid construction and precise machining inspire confidence in its long-term performance.
