Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ Review

Unboxing & First Thoughts on the Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″

After years spent wrestling with less-than-ideal fluid transfer setups, I found myself in need of a reliable, high-flow hose for a recurring project involving propane transfer. The Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ immediately caught my eye as a potential solution. Marshall Excelsior has a reputation for solid industrial-grade components, and the promise of a “Flow-Longer” thermoplastic hose suggested a design focused on efficiency.

My specific need arose from a DIY project that required a more substantial and flexible propane line than what was typically bundled with smaller kits. Standard rubber hoses often kink or degrade under consistent use, and I was tired of the flow restrictions that plagued my previous setups. I briefly considered other bulk hose suppliers, but the pre-made fittings and the specific 1″-20 thread on this Marshall Excelsior hose made it a compelling, albeit slightly more expensive, choice over piecing together a custom solution.

Upon receiving the unit, my first impression was one of robust simplicity. The thermoplastic material felt durable, with a satisfying weight that spoke of quality without being overly cumbersome. The 1″-20 Male Swivel x 1″-20 Female Swivel connections looked precisely machined and seated firmly. It gave me a tangible sense of relief, anticipating a smoother workflow.

Real-World Testing: Putting Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ to the Test

First Use Experience

I first deployed this Marshall Excelsior hose in my workshop, connecting it between a larger propane tank and a smaller portable grill setup. The primary goal was to ensure consistent, unimpeded propane flow for extended grilling sessions without worrying about the hose collapsing or kinking. The 144″ length proved incredibly useful, providing ample reach to position the tanks comfortably away from the grilling area.

During this initial setup, I noticed the hose’s inherent flexibility was a significant advantage. Unlike stiffer, more rigid lines, it coiled and flexed easily around existing structures without demanding excessive force. There were no immediate issues or surprises; the connections screwed on smoothly, and initial leak checks with soapy water revealed a perfect seal. The 1/4″ hose ID definitely contributed to the noticeable improvement in gas delivery compared to my older, narrower lines.

Extended Use & Reliability

Over the subsequent few months, this thermoplastic hose has seen regular use. I’ve utilized it for refilling smaller propane tanks, connecting to various shop tools that run on propane, and, of course, for its intended grilling applications. It has endured being coiled and uncoiled multiple times a week, occasionally getting brushed against toolboxes or workshop floors, and even being exposed to light workshop dust and occasional spills.

Durability has been excellent so far. There are absolutely no signs of premature wear and tear; the thermoplastic material has maintained its suppleness, showing no stiffness or cracking even after being stored in cooler garage temperatures. Critically, there have been zero leaks or performance degradation from the connections or the hose body itself. Maintaining this unit is refreshingly simple; a quick wipe-down with a damp cloth is usually all it needs. Compared to some budget rubber hoses that would start to stiffen and crack within a year, this Marshall Excelsior unit feels like it’s built for the long haul.

Breaking Down the Features of Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″

Specifications

The Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ is engineered with specific performance characteristics in mind. It features a 1″-20 Male Swivel x 1″-20 Female Swivel connection on each end, which are crucial for ensuring a secure and leak-free fit with compatible propane fittings. The hose itself boasts a 1/4″ hose ID, a specification that is paramount for achieving high flow rates, minimizing pressure drops, and ensuring efficient delivery of gaseous or liquid propane.

This particular model extends to a generous 144″ length, offering considerable flexibility in setup configurations. The use of thermoplastic material for the hose construction is a key differentiator, providing a balance of durability, flexibility, and resistance to various substances, unlike traditional rubber which can degrade more rapidly. The “Flow-Longer” moniker isn’t just marketing; it directly refers to the design optimized for unimpeded fluid dynamics, meaning you get more of what you’re pushing through with less resistance.

Performance & Functionality

In practice, the Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ absolutely excels at its primary job: delivering propane. The 1/4″ hose ID significantly improves flow compared to smaller-diameter hoses, resulting in a more consistent and robust supply to appliances or tanks. During my tests, I observed a noticeable reduction in pressure drop, even when drawing substantial volumes of gas.

The strengths of this unit are its high flow capacity and the reliability of its connections. The swivel fittings are a game-changer, preventing hose twisting and binding, which is a common failure point in fixed connections. Its main limitation, if one can call it that, is that its specific 1″-20 thread size means it’s not a universal fit; you need equipment designed for this particular fitting. This isn’t a weakness of the hose itself, but rather a consideration for compatibility. It comfortably meets and exceeds expectations for any application requiring consistent, high-volume propane transfer.

Design & Ergonomics

The design of this Marshall Excelsior hose prioritizes function and durability. The thermoplastic material feels substantial, offering a good tactile indicator of its robust construction. Its finish is smooth and resistant to minor abrasions, which is essential for a hose that might be dragged or coiled regularly.

Ergonomically, the hose is straightforward to handle. The 144″ length makes it manageable for a single user, and the flexibility means it doesn’t fight you when routing it into tight spaces. The swivel action on both the 1″-20 Male and 1″-20 Female ends is particularly well-executed, allowing for easy attachment and detachment without stressing the fittings or the hose itself. There’s no real learning curve; it’s designed to be intuitive for anyone familiar with propane connections.

Durability & Maintenance

Based on my extended use, this thermoplastic hose is built for a long service life. For its intended purpose, it’s a reusable, heavy-duty component. The material shows no signs of degradation even after repeated coiling and uncoiling, exposure to workshop conditions, and regular use.

Maintenance is exceptionally low. A simple wipe-down is sufficient to keep it clean. There are no complex parts to clean or maintain beyond ensuring the fittings are free of debris. Potential failure points are minimal; the primary concern with any hose is the integrity of the fittings, and Marshall Excelsior’s appear to be very well-constructed. It’s designed to last, unlike many disposable or short-lived alternatives.

Accessories and Customization Options

The Marshall Excelsior Flow-Longer Thermoplastic Hose 1″-20 Male x 1″-20 Female – 144″ is primarily a standalone component, and as such, doesn’t come with extensive accessories. However, its value lies in its specialized connections, particularly the 1″-20 Male Swivel x 1″-20 Female Swivel. This specific thread size is designed for particular propane regulators and equipment, meaning compatibility is key.

There are no significant customization options for the hose itself. Its length and connections are fixed as per its specification. The focus is on the high-quality manufacturing of the hose and its fittings, rather than modularity. For users needing different lengths or connection types, Marshall Excelsior offers other variants within their product lines.
