I am fine taking mine without the hose and clamps. It isn't that I am in a hurry, but this is in stock locally.

 

Is there a counterbore for the o-ring to go into? From your pics, it looks like I can still see the Oring, and the hex portion of the ORB isn't bottomed out on your part.

If there's no counterbore, you're just tightening the oring against the spot face?

 

I can see a c'bore. The o'ring isn't captured on the face + sides according to the SAE J1926 PORT dimensions but the c'bore provides a flat sealing face.

 

The O-ring will seal on the counterbore, which the drawing describes as a spotface. In this low pressure situation I didn't see the need in making the part significantly more expensive and machining the tight tolerance multi-angle bevel that is shown in the above drawing.

In other news, the first shipments will go out today!

If you followed us on FB you'd already know that.

 

You would release these right after I searched and searched and searched and finally just cut/welded my factory piece.

Looks like another quality part from Hawley! Still enjoying my reroute spacer!

 

Got mine yesterday. Looks awesome, can't wait to get it installed.

 

Fits like a charm. Don't mind the dirt.

 

Fancy tapered official ORB geometry would indeed be expensive to reproduce. Standard square edge O-Ring counterbore would cost nothing more to do, using the tool that's already making your counterbore (spotface).

Our ORB machining for the same application (engine coolant) was initially done as you have made yours. Ultimately there were issues with it. There's many variables at play that affect how well that oring seals. You are relying on the end user to tighten the fitting to xx oring squish, and that the fitting doesn't rotate (not an issue with yours, is an issue if you use an AN fitting that also get's a hose screwed to the opposite end), and the variable squish of the oring changing with temps/age/coolant contamination. The only thing keeping the oring from expanding and ultimately splitting is it's press between two theoretically parallel surfaces. Coolant is slippery. Aluminum expands when warm. Engine vibrates a lot. Spraying coolant on the track/road is not ideal.

Creating a simple Oring c'bore solves all of this and costs nothing extra. Well maybe adding a 45° chamfer/oring lead to the c'bore with your spot face tool but your edge breaks look nice after the tumbling.

 

Thanks for the overwhelming interest in these parts. We're working to get another batch in as soon as our machine shop can pop them out. Shooting for 1-2 weeks, but I should have a more concrete eta by the end of the week.

 

I'm a bit worried this won't clear my A/C belt tensioner :(

 

I almost ordered one too but looking at the pics wasn't sure it would work with AC. Curious......

 

Please count me in for one, with radiator hose in your next batch. Provided it's been confirmed to clear an NB with AC

 

For me, it'd undoubtedly hit the frame of the tensioner. I could just flip it and run it like standard, but that defeats the purpose as my stocker is doing just fine otherwise.

I may post mine up for sale if anyone wants it sooner than the next batch.

 

so you're saying it won't clear your AC pully?

 

It won't clear the belt tensioner. The A/C compressor isn't hooked up in the picture, but you can see that the outlet would pass right up against the metal bracket of the tensioner and may even interfere directly with the pulley on the tensioner.

 

great idea! will be interested when my cars back together and i have money again haha

 

Psyber - Sorry about the fitment issue. I probably should have noted something about fitment with accessories. None of our cars still have A/C so I didn't give it a second thought.

If you'd rather return it, just let me know.

 

I am pretty stubborn and haven't given up A/C because DC area is a swamp.

I'll pm you later today

 

My car has no A/C or PWR Steering either. Maybe a version, change to have the -16 ORB coming out 90 degrees to the current design would do both.

 

Just as a reminder, we do have these inlets in stock with hoses and fittings!
