Quick Connect trouble

[woodlandfarms]

Well, this is bunk.

I cannot get my Male quick connect off my PTO Hose. Little did I know that there are literally hundreds of these buggers. So, I went to my high end hose shop and they gave me a connector that cross referenced mine.

Well, it did not work. I cut the end off my old hose and took my cut piece back to show them what I had and they said wow, that is weird. They had no match for it. They said that it was uncommon and that I should just replace my PTO connectors with something common...

For those who have the charts, my old piece says FRASTER NV34ZNPTM 01

I am wondering if I change my mower (my only PTO device) now or if my high end hose shop is low brow...

Carl,

It's probably better to get that fitting from PT. I ran into the same problem, with my QD's. The hose-man told he didn't have anything that would fit. In the show room, they had bins of the most common parts and fittings. I took my QD and plugged in different fittings, and found one that would work. If you can find a good source, I would change out what you have for the most common QD availably. Surplus hydraulics has some good prices. If you can, get the next size larger than your hose, and adapt it with reducers. If you spend a little more, you can get the flat face couplers that can connect and disconnect under pressure. The experience level varies in different shops, just have to find one that will impress you with his knowledge. Then ask for him when ever you visit. There are adapters for QD's, but you have to ask.
If you do a search on the Internet for hydraulic disconnect, you can find a lot of info. Northern Tool has a good stock of fittings.

I needed to purchase some of those wen I was building my posthole auger.
It took me a while to find a cross reference because there are so many. The one on my PT has the same number and is made in Italy. After searching the Web I found that the Parker 4000 series should interchange with it, but the cost of the Parker parts in my area was more than what PT wanted so I ordered from PT and had them in 2-3-days.

I was just looking at the Faster Web site, the NV series Quick Coupler has interchangeability according to ISO 7241-1 requirements . The ISO number will help wen looking for a local supplier to cross reference the fitting.

If you are replacing quick disconnect, how about getting some of the flat-faced minimal-spill kind? They are expensive, but if you have to pay to replace your QD anyways, reportedly they allow more flow and are easier to clean.

You can see them on page 279 of the Macmaster-carr catalog.

7241-1 series??? There are series letters after the -1. That ISO # some companies use is almost useless. Within ISO 7241-1 there is ISO-A, ISO-B, and ISO-A ag style. And maybe some more.

Carl, I'm thinking this is a standard q.d. Shops always call things weird or oddball when they don't stock it. Look at the male end, the little piece that sticks straight out the end, is it rounded like a ball bearing? If you can post a nice, clear, close up pic, I can probably identify it. I have a suspicion this is a Pioneer Ag style qd.

 

[BEK]

Forgot the A the number is ISO 7241-1 part A

So.....

My thoughts are this. I really don't want to have to order a part every time I want to fix / add to my PTO system. I think switching my connectors over to something local and more common is the best idea for me.

I have considered going flat face, but I am not sold on them. Quite expensive, and I am not sure of the benefit. And, am I getting an item that I am not going to be able to get additional connectors for (comments, anyone?)

I came home with new connectors. Parker series 6600 (6601 and 6602). Any thoughts? I am not going to install them until I have my PTO issue resolved.

I will try and get a good pix of the end in question. It is not ball but has a pointy activator.

BTW, The shop had handed me the 6601 as the replacement to the FASTER...

 

[BEK]

The Parker can be used as a replacement but it will not couple to the Faster. They are made to different internal dimentions, different ISO Interchange Reference Numbersas well.

 

[ponytug]

The flat face stay cleaner, and have less internal resistance, which means less heat, more (tiny bit more) HP.

Downside is you have to convert all of your PTO coupleres. For me that runs to 10 couplers, which adds up....

Carl, a few years back an autoparts store tried to get me to change my compressed air fittings to their "standard" because it was the "standard". I resisted and have since found my "nonstandard" fittings in Lowes, Northern and still sold at Sears where I originally purchased it. I would not change for the non-standard reason.

 

[woodlandfarms]

So, is Parker any good and are they fairly common?

 

[ponytug]

It is the standard. Lots of detail on their website.
Yes, it is one of the most common, if not the most common.

You could just buy whatever Northern Tool or Gemplers is selling, and then you would have the "standard". You would also have a source that you know you could probably get more from.

The flat face connectors are available from another reliable source, McMaster Carr. I recommend reading their pages on hydraulic hose and couplers.

All the best,

Peter

Carl, even though they are my direct competition, I will say that anything Parker is good stuff. They don't make junk.

Ponytug, you can put flush face on your PT and get adapters to whatever is on your attachments. Then, as the qd's on your attachments go bad, you can replace them with flush face. Check Welcom to Holmbury. They have the adapters.

 

[woodlandfarms]

So WCH... Who do you sell?

I ask because this is a big hose store I go to (they handle all heavy equipment / logging equipment for people who do not have staff repair services).

I am interested in Flat Face, just really have to contemplate the savings vs cost

 

[ponytug]

Dear WCH,

Great point, but wouldn't all I would need is a M&F set of flat face? I already have the others., i.e. when I take it off of the PT, the PT fitting goes on the one of the flat face, the other flat face goes on the PT, and then it is as if the flat face never happened. As I convert others, I just need a single pair of flat face per implement.

So... how much cleaner are they really? How much less oil to do the really spill? Comments?

All the best,

Peter

Woodlandfarms,
I guess I'm missing why you want to change them?

The male one you gave the part number for is $8.50 and the matching female is less than $20.00 at Bailey's on P68 of their PDF catalog.

Bailey's has been around a long time. I've purchased from them before, including the quick connects like you currently have, only a smaller size for my PT425.

The flat faced of the same size as the original flow 3GPM LESS than the original.

Carl, I sell Holmbury. Probably because that's who my supplier dealt with when I opened. I also have some Parker stuff. (shhhh, don't tell Weatherhead) For the weekend user like you, flat face probably isn't worth the cost of converting. They are almost drip-less. It is rumored that the EPA or whoever regulates this stuff is going to require drip proof q.d.'s in the near future. We can't have any oil dripping on the ground you know. I wonder where oil came from?

Ponytug, yes, you only need one set per attachment. I am with MossRoad on this, and how could I miss these in my favorite catalog, Bailey's.

Flat face are more expensive because they are rated for higher pressure. On anything hydraulic, more pressure equals more money. If your unit doesn't require the pressure rating, you don't need them. Flat face will last longer, but in my experience I have found more q.d.'s getting broken rather than worn out. So, it's your decision.
