While I eventually got it dialed in to a fairly steady pressure, I realized I needed a set up with a tank. Very seriously considered taking it back, paying the restock fee, and getting something else. Did a quick search and found this. It works a treat! I get consistent pressure at the brush even with long sprays. It's true, there are no instructions, but there is a video out there of someone assembling part of it. I'll give a few pointers here, but these will be specific to the Avanti compressor from Harbor Freight. 1.) Pick up some new O rings, 1/4 in ID 3/8 in OD. The rings that come with the kit aren't great and I over tightened the first time I tried and destroyed two of them. 2.) Pick up a 1/4in by 1.5 in Nipple, I'm adding a link here, but I got mine cheaper at the local hardware store. There are other options, but this is what they had and it works. https://www.desertcart.com/EDGE-INDUSTRIAL-Brass-Nipple-Length/dp/B07DCF9J2J/ref=sr_1_4?crid=346J2P7P6OVIU&keywords=1%2F4%2Bby%2B1.5%2Bnipple&qid=1652562653&sprefix=1%2F4%2Bby%2B1.5%2Bnipple%2Caps%2C93&sr=8-4&th=1 3.) The cutoff sensor on the Avanti is the same as the one that comes in the kit (3kg on, 4kg off), so no need to mess with it. 4.) You'll need either thin open end wrenches of appropriate sizes (12 mm and 14 mm) and an adjustable (crescent) wrench, or you can get away with the crescent by itself. To assemble, 0.) Attach the feet to the tank. 1.) Unscrew the regulator from the compressor. This can be tricky, but I found that using an adjustable wrench if I went lefty loosey on the bolt where the airbrush hose connects, the regulator unscrewed from the compressor. OR use a THIN* 14MM open end wrench and unscrew the connector between the compressor and the regulator directly. (THIN means 5MM or less) 2.) Remove the feet from the compressor 3.) Attach one end of the pipe to the square 90 by fitting it inside the opening and pushing two o-rings to the fitting. Loosely screw the connector on. Do not tighten as you'll need to adjust it later. 4.) Attach the other side of the square 90 to the opening where the regulator came out. Snug it down but don't tighten yet, you will need to ensure the flat side of the pipe attachment is on the front and back. The pipe will need to be vertical 5.) On the tank there is a smaller opening and a larger (1/4 in) opening, put the appropriate fitting into the smaller opening where the larger part is facing out 6.) Set the compressor on the tank fitting the pipe into the opening of the fitting you just placed, you may need to adjust the positioning of the pipe vertically to ensure it seats in both the upper and lower openings. Once that is done, pull the compressor off the top of the tank 7.) With the compressor off the tank, loosen the square 90 to a position where it is possible to tighten the compression fitting on the pipe, and ensure it is snug. Make sure the font and back have flat sides on the bolt. Tighten the Square 90 into the compressor completely ensuring the pipe is vertical. You'll see the compression fitting is nearly flush with the compressor, thus the need to have a flat side there and not a corner. Set compressor aside 8.) put the nipple into the other opening on the top of the tank, and put the rounded 90 on the other end of the nipple 9.) If you have not already done so, remove the connector from the regulator that was used to connect to the compressor, and screw the regulator in to the rounded 90 and tighten ensuring the moisture trap is down. 10.) Add the Red fitting to the of centered hole toward the top 11.) Add the drain fitting in the bottom 12.) Set the compressor back on the tank 13.) Use the included screws and nuts to attach the feet of the compressor to the tank (it will be a tight fit due to the nipple being vertical. It is possible to change this arrangement, but I didn't want my regulator sticking out from the compressor and tank.) 14.) Snug the bottom of the pipe to the fitting 15.) Plug the compressor in and fire it up. If you got really lucky you'll have no air leaks. I didn't get lucky and had to do a little rework on a couple places, but it was pretty painless. Soapy water makes it easy to see where the leak is. Note: it's going to take a some time for the compressor to kick off. Just about the time you think you messed up is when it will shut off. Review: Take your time with the conversion and everything will go great! - I ordered this tank conversion only to receive it with some fittings that were not even cut. Returned it for another and everything appeared ok. Some fittings even with teflon tape were loose, so of to Ace Hardware for Permatex blue thread lock. That worked great, but while connecting up the compressor discharge pipe, the Parts Gremlin, ( If you build models you will know what I mean ) got one of the rubber rings that act as a furrule for the compression fitting. Off to Ace again. They have a good inventory of O rings. I did need to order a fitting to complete the job. Remember, if you need any fittings they are BSP fittings not ASE. Now that the conversion was complete started up and worked perfect!!! No Leaks!!! ## Features - 【3L Airbrush Tank Kit】Large capacity, comprehensive accessories, easy to install.

Please measure your compressor's outlet threads and mounting hole distance to avoid misfits. **Q: How long is the included tubing? Is it extendable?** A: The metal air hose is 4.33" long(Dia.0.31"), plastic air hose is 6.69" long(Dia.0.27") long and cannot be extended. Please confirm your compressor's outlet is within this distance from your air tank location. **Q: Why is air leaking from the connections?** A: Leaks are almost always due to improper installation: (1) Seals not fully seated in grooves, (2) Under-tightening, (3) Missing tape. Tighten firmly but do not overtighten—this damages threads. Check each joint systematically. **Q: Are the mounting holes adjustable?** A: No. Hole locations are fixed at 5.9" long, 3.9" wide spacing. Some compressors require drilling new holes or using an adapter plate. If your compressor's holes don't align, do not force it—this will damage both units. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It goes between the compressor and the regulator, and it works. *by M***R on May 14, 2022* A week or so ago I picked up the better airbrush kit at Harbor Freight.

No Leaks!!! ### ⭐⭐⭐⭐⭐ Ophir Air Tank Kit is Amazingly Helpful *by N***E on April 9, 2022* This kit makes my small airbrush compressor perform so much better. There are no install instructions but it’s pretty much common sense so if you don’t have common sense stop reading right now. Everything will to be secured with need the Teflon tape to prevent air leaks, and trust me it’s not worth the time it takes to skip this step just to have to go back and re do all connections. I skipped and ended up hating my life while I went back to do things correct. All in all this unit is great and now my compressor doesn’t have to run non stop while I airbrush which is going to allow it to last so much longer and not have to strain when I work on larger projects while also allowing my airflow to be consistent and constant. This is a absolute must have if you have a small airbrush compressor without a tank! ## Frequently Bought Together - OPHIR 3L Air Tank Kit with Adapters Tube for DIY Airbrush Compressor, Black Air Tank Conversion Kit for Hobby Model Air Compressor Storage Tank - TIMBERTECH Airbrush Hose, Premium 10ft Nylon Braided Airbrush Hose with Airbrush Quick Release Disconnect Coupler, Plug 1/8" BSP Male and Female Hose Connection - Master Airbrush Cleaning Kit 13-Piece, Airbrushing Cleaner Set with 1 Glass Pot Jar, 5 Cleaning Needles, 5 Brushes, 1 Wash Needle & How-to Airbrush, Cleaner Set Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/186444617-3l-air-tank-kit-with-adapters-tube-for-diy-airbrush](https://www.desertcart.vu/products/186444617-3l-air-tank-kit-with-adapters-tube-for-diy-airbrush) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-16*
