I think they are way overpriced. I am using an older version of this, which I expected would die quickly. 4 years later still works perfectly and still accurate.

I have one we use all day in our shop- it's great quality.

Where can i find a high quality presta fitting for my air compressor? I just have a shrader head and it works with presta valve core removed most of the time but doesn’t transfer enough airflow for stubborn tires (too much leakage). I would also be fine with an adapter that works well but it needs to be able to mate to presta valve with core removed so standard valve thread adapters don't work. I used one when i used to work in a shop and have seen them in shops recently but haven’t had any luck finding one to purchase.

edit: i just found some, don’t know what i was smoking last time i couldn’t find any. Still curious of which is best for presta with core removed for mounting tubeless.

I use a blowgun nozzle with a variety of 1/8 NPT fittings to a press-on presta valve adapter to get the most airflow for seating tires. Never fails me.

Look at EVT efficient velo inflators, they are awfully expensive but allegedly super high quality.

I honest could care less for a gauge on a presta compressor inflator that would be used just to setup tubeless tires, at least in my case I prefer to use a floor pump and a good gauge, no need for a compressor.

For tubeless setup I’d prefer something like these which is single hand and easier to use compared to the more finicky ones…

If you want the best, you want EVT. If you want something that works well, dirt cheap, and available at any hardware store, you want 6” of aquarium tubing. I forget the ID, but just wide enough to slide over the valve stem.

The convenience of using a compressor with an inflator and good gauge should not be underestimated. Some call it lazy, I call it saving my energy for the climbs. 😄

For just seating tire, the blow nozzle is hard to beat.

all replies are much appreciated. I think the prestaflator mini will best suit my needs.

While I'm not as big a fan of Park Tools the past few years (their truing stands are inaccurate, poor aligned junk these days), I do like their inflator. It's been super accurate also.

If you are chasing maximum flow, you are limited by the smallest passage in the system...which CAN include the hose fittings. If you have swivel hose, it's likely that you are necked down to 1/8" instead of the typical 1/4" of small hoses.

Shop-quality automotive inflators (Blue Point is an example if that that isn't super expensive) will typically be listed as high-flow/given a rating. A simple, diving-bell style presta adaptor (SKS, Prestaflator, Silca, et.al) that screws in/presses into/snaps on typically has a 1/4" bore. Milton makes a screw-on replacement for the face of a typical ball-type Schrader head that clips into the valve/adaptor, making things much less fiddly.

Consequently, I don't really use the blow gun for anything but drying parts off, now; my inflator has almost 2x the airflow capability.

I have an old Harbor Freight inflator I grafted a dual head from a broken pump. The gauge is about 10 psi off but pretty cheap. I use it to seat tubeless tires and sometimes filling tires. I always use a good gauge to check/adjust pressure.
Currently $9.99

Why adapters and fittings? It seems like those could impede flow and would take extra time. An blower nozzle directly on the valve is simple and works perfect for me.

I use the ribber tip that came with my air gun kit. Remove core, place tip on valve core and squeeze air gun lever.

Yep, that's all you need.

The Shrader-Presta adapter for the stem doesn't work? I have used those since I got my Trek in 1984 and they have never failed.

given how expensive the prestaflator stuff is, I expected better quality, but once I got one in hand, I realized it's basically just a harbor freight quality tool.

FWIW, I prefer this silca chuck. with the old bell-type ones, there's less clearance between knuckles and cassette cogs (or disc rotors), and by simply angling the hose off to the side, this one gives better clearance.

Bicycle Disc Wheel Adapter – SILCA

I don't use the blower because mine is absolute craptastic quality (lower quality than the prestacycle inflator). I do need a better one, but it's a pretty low priority item at this point.

Seems to me even the cheapest ones work fine and need no improvement.

If the op is looking for the presta head mainly to seat tires then a simple $5 blower nozzle is superior to anything else out there ime.

It's a slip on one I had sitting around. The schrader threads of the adapter fit in an NPT 45* elbow and makes it easy to stick on valve with the handle at an angle out of the way of the disk brake/cassette. I made it 15 years ago out of random parts in my garage, now it's used daily at my work space in the shop.

trust me, mine sucks. the valve is sticky and it's not really controllable. I've disassembled it the best I can in an attempt to clean/lubricate it and it doesn't help.

I use the best of what I have. it does the job and I've no complaint about it. Would I use the blower with a rubber tip if I had a better blower? possibly. but what I have now sucks. so I don't use it.
