3000 psi receptacle retrofit device changes to 3600 psi made by Chesapeake?

[OklahomaWes]

I was filling up at the On Cue station in N. Okc and a OGE employee driving 3000 psi bifuel truck, told me that Chesapeake had made a retrofit device to attach to a 3000 psi receptacle so you can use the 3600 psi refuel nozzle pumps. Anyone know where to buy one of these units? Told they were selling for about $25-20 bucks. Thanks Wes

Call me conservative, but I don't think that it is such a good ideal to fill 3k tanks with 3.6k psi fills.

It is forbidden by NFPA 52. In other words, it is illegal.

Oh i found out they are being used by ONG, not OGE.

Given fact that many of ONG locations often just have 3,000 or 3,200 pressure anyway on either the 3,000 hose or the 3,600 hose, then the risk is very low. I would bet that NEITHER an ONG worker NOR a Chesapeake worker are routinely filling a 3,000 psi system to 3,600 pressure. Often, just the 3,600 hose is functional on a particular ONG refueling location, so it would be necessary to use the retro-fit connector to get the available 3,100 psi pressure that the station has to offer.

Don't blow this miniscule anthill into a Mt St Helens Volcano !! I'm certain that safety as it the forefront of EVERY employee using CNG at both companies.

There is nothing more frustrating than to pull in to station with empty tanks only to discover that they only offer 3600psi. I added a p36 nipple to allow one of my vehicles to by filled from a 3600 station. I monitor the pressure gauge that I had installed under the hood and shut the pump down at 3000psi. (I have since sold the van and changed the nipple back to a p30)

Using a adapter like this is a good way to get some one hurt. I dont think it would blow up but there is no situatuion worth doing something dumb like this. This is why TGT does not sell parts over the counter to non qualified or non licensed techs. Only a qualified station operator should have one of these.

By the way, 3000psi systems according to NFPA-52 are also supposed to be able to be built to withstand something like 1.5 times more pressure than their maximum normal service pressure, so that is 7500psi, [moderator note: his math is incorrect here, 1.5x is 4500 psi] so nothing bad will happen with 600psi more (if your even lucky enough to get a full 600 more), especially since you must also realize that even after a fresh fill, then you start driving away and in just a few minutes the tank has already lost a couple hundred psi just from driving and with the tank cooling down and such. I realize NFPA says it's 'not legal' to do it so that is another discussion, but technically speaking the system wont blow with 3600 psi. Now if the system blew because of some other problem and people then found out he had that 3600psi receptacle installed, they would all blame it on that and he would catch hell for it...

If you have 3000 psi tanks then by all means do not circumvent safety devices on your vehicle to fill at 3600 psi dispensers.

I believe this falls into the category of furthering unsafe and illegal activity. Thread closed.
