Hydraulic hose comparison: Napa vs Parker

- I needed two new hoses for my loader, and decided to do a comparison between a couple local places. Not sure there is much difference between the two.......you be the judge.

Napa made a 1/2" hose with 3/8" pipe thread and the Parker store made you a 3/8" hose with 3/8" pipe thread. I work for MFCP Inc. and make Parker hoses all day long. Weatherhead is a quality hose as well as Parker...
I finally broke down and bought a couple hundred feet of hydraulic line, basic fittings and a press. No farm can run into town and pay $200 for a hose every time a hose blows… our only choice around here is “House of Hose”…go figure
What do you use for a crimper?
I've always had good luck with NAPA hydraulic hoses for my 2038r John deere!!
I can't say anything about the difference between brands, and nevr really saw much in practice, but I can tell you that the larger hose MAY have shorter life when flexed. It will also be stiffer under pressure, put more load on the fittings, and more likely to crimp at the tightest bend point. The general rule when I was doing a lot of hydraulics was to use the smallest diameter hose suitable for the flow to get maximum life, and, when practical, use coils to protect the hose from damage (the 'springs' that go over the hose) in exposed areas. Protected areas and high flex, the coils can abrade the case and shorten life. Someone else already mentioned MPa is megapascals.
The Weatherhead hose is the finer hose. It’s the name brand that has been the industry standard for almost 100 years. Weatherhead fitting (by the appearance ‘U-line’ fittings were pressed on a standard Weatherhead T-400 press. (‘Eaton’ is Weatherhead brand)…and just for your information, EVERYTHING is made in China. The Napa hose is ‘costco’ type hose…from the cheapest supplier…always go with Weatherhead if you can’
weatherhead eaton is 1/2" ID hose
parker is 3/8" ID hose
-the inside dimension shouldn't be different without asking you
- bigger ID gives you more flow through the hose.
- weatherhead/ Eaton used to be called Imperial Easton ( well known name brand)
-Parker is very well known in the hydraulic world
- the fittings are also usually the brand of the hose
-bigger hose is a lil more expensive
I usually use the Eaton hoses for hydraulics, the parker is better at pneumatic. But they both work well. We use both at pratt and whitney for machines, the Eaton seems to stand up to oil's better, but push lock parker on air lines is stupid fast.
The Parker Assembly Number calls out male rigid npt 3/8 thread on 302 series 3/8" ID hose at 35" OAL measured end of thread to end of thread. NAPA doesn't consider what they made to be an 'assembly', they sold you 1/2" hose instead of 3/8", and charged you for 3 feet while only giving you 35". Eaton and Parker are both good brands.
MPa = Megapascal. 33 MPa is approx 4790 PSI.
Thanks!
Surprised to see WeatherHead from a NAPA store. My family owns a Hydraulic Distribution Company in New England and we are a Gates distributor. NAPA is nationwide a Gates Distributor as well. Gates and Parker are top in the game, although from a Quality standpoint, Gates surpasses all. WeatherHead/Eaton have declined in quality over the years.
Side note- Those are cheap assemblies! Those would be north of $100 at our shop. And, both of those hoses are near identical in construction to be honest.
Thanks. May the independently own franchise NAPA's have some choice in vendors.
MPa would be mega-pascals I assume? I find it odd they also use commas for decimal points on a made in USA part, would make sense for a European part.
It appears to me that both hoses have low quality out side rubber. It only last 5 to 10 years before burning off and exposing the steel braid. To make it last,you need to cover it with shrink or final tape.
The poor quality out side skin is why the old one failed.
My NAPA is locally owned so I'll go there first before I go to a Parker store since it's a company store. Both are good quality and naturally Parker has way more hydraulic fittings, but you can't buy auto parts there can ya?
That Parker distributor i went to here is independently owned. No auto parts but they do have hoses, seals and other industrial supply items.
Parker Stores aren't owned by Parker Hannifin.
@@ChrisSmith-kw4gn What you said. Parker own the ParkerStores in some non-US locations but in America, they are locally owned and independent.
our tax is 15%
Dude.
ALL hose confirms to a SAE standard. You really need to spend a few minutes,,, or hours looking online on primers to understand what you are desiring to understand. :-). 100R2 is NOT compatible with 100 R16. you got screwed due to not being prepared.. HINT. go online to a hose suppliers and read EVERYTHING you can in the resource sections available everywhere... how can you accept hoses with various IDs and different SAE specs? Sheeez
