Let’s Talk About Marshall Excelsior Lp Thermoplastic Hose 24″ 3/8″ Mnpt x 3/8″ Ffs
Let’s dive into the world of RVs and propane systems, and specifically the unsung hero that keeps the gas flowing: the Marshall Excelsior Lp Thermoplastic Hose 24″ 3/8″ Mnpt x 3/8″ Ffs. This isn’t exactly a flashy piece of gear, but it’s absolutely critical for safety and functionality when you’re relying on propane for heat, cooking, or powering appliances on the road. The Marshall Excelsior brand is known for reliable RV components.
My interest in this particular hose stemmed from a nagging concern about the aging rubber hose on my own travel trailer. Rubber deteriorates over time, especially with exposure to the elements, creating a potential leak hazard. Thermoplastic hoses are known for enhanced durability, so this seemed like a worthy upgrade.
Upon receiving the Marshall Excelsior Lp Thermoplastic Hose, I was immediately impressed by the overall build quality. It felt sturdy and well-constructed. The brass fittings looked precisely machined, and the thermoplastic material itself felt noticeably more robust than the old rubber hose I was replacing.
Compared to a generic rubber propane hose, the Marshall Excelsior hose felt like a clear step up in quality. I also considered a stainless steel braided hose, but those can be overkill for a simple trunk line application and tend to be less flexible. The thermoplastic offered a good balance of durability and ease of use.
My first impression was definitely positive; I felt a sense of relief knowing I was installing a safer, more reliable component into my RV’s propane system. It’s not the most exciting piece of gear, but peace of mind is priceless.
Real-World Testing: Putting Marshall Excelsior Lp Thermoplastic Hose 24″ 3/8″ Mnpt x 3/8″ Ffs to the Test
First Use Experience
The first time I used the Marshall Excelsior Lp Thermoplastic Hose was during a weekend camping trip in the Ozark Mountains. I installed it as the main trunk line connecting the propane tank to the regulator on my travel trailer. The weather was fairly mild, but there was a considerable amount of humidity in the air.
Installation was straightforward, thanks to the standard 3/8″ MNPT and 3/8″ FFS (Female Flare Swivel) fittings. No leaks were detected after a thorough soapy water test. The hose’s flexibility made it easy to route around other components in the propane compartment.
There were no surprises during that initial camping trip; everything worked flawlessly, and I had propane for cooking and heating water. This alone was a significant improvement over my previous system which required constant monitoring for leaks.
Extended Use & Reliability
After six months of consistent use, including several camping trips in varying weather conditions (from hot desert environments to colder mountain climates), the Marshall Excelsior Lp Thermoplastic Hose has held up remarkably well. There are no signs of cracking or deterioration in the thermoplastic material. The brass fittings still look as good as new.
The hose is exposed to direct sunlight and road grime during travel, and it seems unaffected by these conditions. Cleaning is simple; a quick wipe-down with a damp cloth removes any accumulated dirt. I’ve inspected the fittings regularly and haven’t noticed any loosening or corrosion.
Compared to my previous experiences with rubber hoses, which would often develop cracks and require replacement every year or two, the Marshall Excelsior hose appears to be a significant upgrade in terms of longevity and reliability. The Marshall Excelsior Lp Thermoplastic Hose is proving to be much more durable.
