stuart Posted May 22, 2021 Report Share Posted May 22, 2021 32 minutes ago, John R Martin said: THe HP hose that I consider has dubious fittings and/or materials with no swaging has been returned to Rimmers following their agreement to a full refund including return postage. They still maintain they have had no complaints with these items. On the advice from specialists here on the Forum, I have purchased another hose from a supplier in Chiswick. It looks quite similar to the returned one with no proper swaging but seems to be less flexible and better braided externally: but who am I to judge? The Chiswick item, judging by the packaging, came in by a container from India. I have fitted this to the car but have decided to carry the original pipe in the boot as an assurance. If anyone knows where I can buy a properly swaged pipe, made from the correct materials with a stated test pressure then I would appreciate their advice and sleep soundly at night; price of no concern! Thats actually a typical answer from Rimmers Im afraid, theyre known for it. Ive used TR Shop supplied ones with no problems Stuart. Quote Link to post Share on other sites
Rob Salisbury Posted May 22, 2021 Report Share Posted May 22, 2021 You could try Chris Witor of the Triumph 2000/2.5 bunch, he has a selection Pi hoses that are swaged, may not be the same length but will probably be OK. Cheers Rob Quote Link to post Share on other sites

The ones you’ve used with no issues do they look similar to the faulty one above?. Cheers Mark. ps would it be worth fitting some pipe clips ?

AndrewMAshton Posted May 24, 2021 Report Share Posted May 24, 2021 Hello, I used Merlin Motor Sport for my swaged fittings, they are at Castle Coombe Race Track, Goodridge suppliers, if it is good enough for F1................., it was expensive but it looks good, cheers, Andrew Quote Link to post Share on other sites

Hamish Posted May 24, 2021 Report Share Posted May 24, 2021 You need to find your local truck or hydraulics suppliers I use lining and hose in congleton https://www.liningsandhoses.co.uk trade counter bloke alway so helpful to try and help me out with my “projects” even though I only spend a few quid.

Phil Read Posted May 25, 2021 Report Share Posted May 25, 2021 If Rimmers have a laissez-faire attitude to what could be a very life threatening situation I would take the issue up with the DVSA or your local trading standards, thats what they are there for. Quote Link to post Share on other sites
roy53 Posted May 26, 2021 Report Share Posted May 26, 2021 Must admit this looks very unsafe ! a test would be interesting , but 1 fail is 1 to many. Roy Quote Link to post Share on other sites
Waldi Posted May 26, 2021 Report Share Posted May 26, 2021 A new hose will probably pass a “pressure test” (at what temperature and pressure??). In industry, new vessels are normally tested at approx. 1.4x design pressure. And design pressure is higher dan maximum operating pressure. For materials exposed to elevated temperature, the test pressure (typically at ambient temperature) is further increased to take the loss in strength in consideration. In this case, degradation of the rubber compound and temperature (radiation from engine) will lower allowable pressure in order to maintain a sufficient safety factor. So a pressure test on a new hose with say 105 psi means little (nothing). And if the incorrect grade/quality of hose is used, it is simply not suitable. Waldi Quote Link to post Share on other sites
John R Martin Posted May 26, 2021 Report Share Posted May 26, 2021 Hi All, Judging by the level of interest in this topic and being specifically related to members' safety, I trust the Parts Quality Initiative (PQI) team is taking a very active interest. I look forward to their repoart in due course. Cheers John Quote Link to post Share on other sites
RogerH Posted May 26, 2021 Report Share Posted May 26, 2021 Hi Folks, this is a very concerning topic. Nobody has contacted the PQI operatives (Ian and me) to look into this issue. However there is a process and the process is so far working. The purchaser has a complaint and he has been in contact with the supplier. The supplier on this occasion appears (eventually) to be doing the right things. They have offered a refund/replacement (upgraded) and has said they will investigate as and when the broken pipe is returned to them. I know that they do not do things to speedily so any result for the investigation may be some time in the future.. It would be noce to have the pipe in my hands so I could see what is actually going on. I am surprised that the hose does not have a swagged clamp/clip to hold it in situ - but from some of the pics and comments it looks normal !!! We'll keep an eye on any result that may appear. If the purchaser or Inge would like to fill out a PQI form we could then start at this end. https://trsdf.uk/projects#PQIIntroduction Roger Quote Link to post Share on other sites

So is this the same as Rimmers and the others? Also is this the only failure? I suggest that if this is the case would it not be worth waiting for them to report back .

saffrontr Posted May 28, 2021 Report Share Posted May 28, 2021 Salutary tale indeed. I have had one of these hoses with the unclamped red ends fitted since 1999 when it was changed during an engine rebuild and I have many images of the engine bays of other TR6's showing unclamped red ended hoses, in fact have a look on the TR5 forum and you will see that CP2 which is currently for sale at Sherwood Restorations also has one. Do I and others have a problem I guess that is the question that can't be answered unless we have our own pipes tested? Maybe I should replace mine anyway as it is now 22 years old but what would I replace it with? In the short term I am going to fit some pipe clips at least until someone comes back with a source of pressure tested hoses. Derek Quote Link to post Share on other sites
RogerH Posted May 28, 2021 Report Share Posted May 28, 2021 Hi Derek, after such a long time I would suggest that the red ended pipe is intrinsically safe. Inge did show concern over the internal diameter of the new pipe. This new pipe failed after a very short time. indicating that perhaps there is a problem with the sourcing of this pipe, I'm sure Rimmers will come back with good info.

I know that Aeroquip manufacture a screw together fitting but it is not suitable for rubber but ok for PTFE tubing. I am not certain what the principle is of this fitting that has failed? Bruce.

The failed hose had the simple principle of push on, nothing at all to hold the hose to the fitting. It may have worked if it had been done the same way as the old hose with a more aggressive barb and a thick hose with internal steel braiding. We had to use a hacksaw to get the old fitting loose from the old hose. Quote Link to post Share on other sites
Peter V W Posted May 28, 2021 Report Share Posted May 28, 2021 This is my hose, from moss. I’m no expert but it looks a better option. Quote Link to post Share on other sites
