Question: Okay, I'll bite.  Why don't you need a fuel filter for this hose and not the others?  I don't see that a fuel filter is included with this hose.
Document: I was going to purchase the shorter hose but it required a fuel filter which would need to be periodically changed. I did not like that idea so I bought this hose instead. One and done and glad I did.
Because this pressure is so low it will not be able to squeeze out the oily plasticizers from the rubber in the hose and does not need a fuel filter.Bradford AustinEnerco Mr Heater4560 W160th. St.Cleveland, Oh. 441351-800-251-0001 ex 868bradford.austin@us-egi.com
I bought this hose because with it you do not need to use a filter with your heater. Have used it for a couple of years now and still going strong.
Just what I needed. This hose eliminates the need for a filter. A little pricey but when dealing with propane safety is of the utmost importance.
This propane hose for a Mr. Heater "Buddy portable Heater" is "A Must Have Item" for use in long term without heat emergencies, or several days use while camping in cold weather. "This Model # F273704 States That It Does Not Require A Fuel Filter", like other hoses do. I recommend This Hose Assembly" but not the "Seller/Shipper I purchased it from, "Very Slow Shipping" !
This hose is a must with the buddy heater for extended use.The cylinders tend to empty quickly and are costly.This specific hose does not need a filter with it.
So you don't need the filter but you have to work with a hose that doesn't like to straighten out or is more difficult to work with because of this stiffness.As far as the hose with the quick coupler, this is only available to be used on the Big Buddy MH18B heaters.
I have used this in the cold in Maine, and it did not stiffen up much at all. This model is designed so that you don't need the filter assembly, which is very convenient. Seems well made.
This is great. Does not require additional regulator if you use this hose. Did not see this hose available in big box stores. If I had to say one thing negative about this, I wish the hand crank fitting was a stronger material. It is plastic. All in all good product at a great price.
Just as expected. I remember reading a review that a user needed to have an empty 1lb canister on the other side of the heater to get it to work. This isn't true, you just need to purge the hose of air, or for a better description...  just wait for the propane to travel down the length of the hose to the heater.
Answer: The composition of this hose does not leach oil . If you buy a cheap hose it will leach oil and damage your heater.
