Heater Core Supply and return lines - sizing


Recommended Posts

Replaced my heater core lines with High temp hose & sleeved both each with a piece of heat shield. Heat shield will reflect most of the heat, cost $5 to 8 a foot. I used 3'... Dave

Yeah basically what I plan to do. What size or where did you get the heat resistant hose ........

Parker.com Or mcmaster.com would be where I'd start. Parker has local stores as well.

John,

Now that I am not on my phone...

Below is 1/2" parker heater hose, silicone std wall. Use this hose and put it inside the firesleeves below. Also, this stuff will work as conduit for electrical or pneumatic lines.

They also have "firesleeve" that is a bit more stout.

The brouchure on the firesleeve is at the below link... Rated at temps: Continuous: -65 to +500°F * Intermittent: -65 to +2000°F. Honestly, this stuff should do you, 85psi rating, 500F continous rating... If you have things under your hood over 500F you have some serious heat radiation problems and will want to heat wrap or coat the crap out of those twins.

Let me check through it and see... I'm not at my computer today. As for where to get it they usually have either Parker sales shops or Parker dealers around most industrial towns or some farm towns.

Ok John, back from two solid days of wrenching back at the family farm. (the 02 is looking MUCH better though!)

1. I am not sure what the correct ID and OD is, I am pretty sure that it is likely a standard, and could be either measured or just ordered from NAPA.

2. If we look at the data sheet from the first link I posted, it looks like it is recommended for use as heater hose in cars, trucks and buses. See row 3 in the below table. Also, the Parker hose is rated to 350F by itself. Probably not too much more than the stock rubber hose, but it is a silicone hose and may cost similar if you can find a local Parker vendor.

3. The hose in the first link is the actual hose... The second links are for the fire sleeves that will add a good amount of additional insulation and protection from hot glowing metal and hot air. They won't however, keep the internal hose completely cool.

also...

I've used the fire sleeves before in race applications, and basically they are just sleeves that you run your hoses in. I think we ran fuel and air lines in them if I recall right. You may be able to even use the fire sleeve on the stock heater hose and save some money while getting pretty good heat protection...

Also, below is a list of the parker locations in NC, based from their site. I've used the parker shop near the family farm for years... Swagelok fittings, hydraulic hose, etc... but there may be a better place to find what you need. They have just worked well for me.
