  • Coolant Hoses Moss VS Roadster Factory

    As posted in another thread, I'm getting my 6 on the road after 8 years in storage. I'm replacing all the hoses and I see that the Moss green hoses are half the cost of the RF hose set Are the RF set worth the extra cost. Thanks

    personally i would not go back to green hoses. got my car with them and they would not clean up. i just replaced mine and went with the rubber black ones.

      To judge a coolant hose, you really need to view a cross-section of that hose.

      What you want to see in that cross-section is re-enforcement with some type of cords around the inner perimeter of that rubber.

      A cheap water hose will have no re-enforcement, or very minimal fibers- and- will not be durable.

      An exception to this was the original two heater hoses on my '72 TR6 which lasted over 40 years- but they were so thick that they didn't need cords- however, they cracked apart in chunks.

        When I acquired my 71, 6 years ago, one of the first jobs was to install a Moss-sourced set of green hoses. I replaced them again last year with an all-silicone set, as the green hoses had deteriorated - the ends were splitting, the green cover layer was fraying and peeling off. Personally, I would not use those again. Hopefully they have a better-quality product these days. My 2c.

          My TRF supplied green hoses look fine 10 years later.

          I have ever found TRF quality equal or superior to that of their competitors. The sole exception I have found in 40 years of dealing with them is the Surrey hardtop front seal is too short. I use the MOSS for that only.

            I think this picture shows what Walt was talking about...This is the green silicone hose from Moss, but at the time you could only get the big ones in green silicone....when I got a few bucks ahead, I bought the rest of the hoses in black silicone from British Parts Northwest.
            So far so good; but it'll take a few more years of 'testing' before that's a what you might call an 'endorsement'.
            I don't have the link, but there was a source for complete silicone sets in colors.

              I bought TRF green hoses back in 2009. No issues until last year when I noticed a slight tear at the bend in the upper hose. Its not leaking and I only noticed it at the end of the season when I was checking the car over after the trip to TRials.

              I'll replace it this spring, most likely with a new hose from TRF.

                I do not know about TRF hoses (otherwise very pleased with other parts) but I found that the smaller Moss green and the black rubber BPNW hoses were a sloppy fit. The BPNW wire clamps would bottom out before a snug fit on the fitting. So ordered Moss green. These were a worse fit particularly on the heater and manifold pipe so ended up using the BPNW hoses throughout for uniformity, but with jubilee clips.

                  I installed a complete set of the TRF black hoses (including the two heater hoses) about a year ago, on the '72 TR6.

                  They each one fit perfectly, very strong, very tight, the right curves and bends.

                  They sell different kits for the top radiator hose with & without that vacuum unit, so you need to know if you have it when ordering.

                  I heated each end (with a heat gun on medium setting) for about 10 seconds, then slipped on the new hoses (heat the old ends for easy removal).

                  No leaks, heavy duty rubber with thick inner cord came with the Jubilee Clips which were Factory style.

                  They sell a packaged kit for around $75.? IIRC.

                    What about those stainless steel hoses to blink up the engine bay?

                      I personally would use TRF every single time over Moss. I limit Moss to "nothing else available or can't get it in time anywhere else and have to have it". Only issue with TRF is that they backorder things quite a bit. Have had numerous quality issues with Moss.

                        Depending upon how the rest of the engine bay looked that could be like putting lipstick on a pig.

                          I agree that the Moss/BPNW (Uro) hoses are a sloppy fit and not particularly stout. Has anyone tried Mackay hoses from Australia? I bought an upper hose for my '69 but have not installed it. It appears to be thicker and has better cord reinforcement, also the surface texture is more "vintage". But I am awaiting the re-engineered black-yellow striped set currently on offer so I may never install the Makay.

                            I got my set from this supplier in the UK.

                            Note - the hoses they provide for the TR6 are for the PI model. The Carb model uses a couple of additional hoses, that connect to the heater tube running through the intake manifold, which the PI doesn't have. And, they dont (or didn't when I ordered) have the top-hose for the later US TR6 that had the Air pump etc. All hoses are slightly longer than needed, allowing you to cut them precisely to length for your car.

                            Beyond colour options, they also have finish options, including matte etc.: http://www.classicsiliconehoses.com/product-options/

                            Here is a pic of my rad top-hose after installation. I got the gloss finish, which is super-easy to keep clean.

                            This company is a bit of a mom-n-pop operation - sometimes a bit slow to respond, but they have a good well-constructed product, and are willing to work with you. NFI.

                              I got the same set Kieth did, from the mom and pop shop across the pond. Like he says, they're a bit slow, but they came through with all the hoses I need for my 73.
                              Planning to fit them and a larger e-fan before the onslaught of the weather hell they call summer in these parts.
