Milton (S-210) 1/4" NPT M-Style Coupler and Plug Kit, (12-Piece) (4-(Pack))

Have replaced all of the air fittings on my air tools with these. The fit and design tolerance are better than the original fittings and way better than the fittings available at big box stores. They lock together tight, with no play. They are heavy relative to other brands. No air leakage out of any of them. I've shown them to two other contractors and they were both impressed and plan to switch over to this brand when they rework their air tools. Classic case of paying for better quality. These work better than anticipated. I would rate these as best quality.

The seller (Tool Deals) shipped this quickly in OEM packaging.This is a handy, inexpensive starter set with two female couplers; two 1/4 inch pipe female ends and eight male ends. That's probably a good mix for most people.The product itself was as expected; excellent. Milton developed the "M" style coupler and the original is still the best in my opinion.I have some air tools that have had Milton couplers on them for many years. The brass on some of the female couplers is visibly worn on the exterior where they've been dragged around on the concrete over the years but the couplers themselves continue to work perfectly with very, very little leakage. The new ones look exactly like the old ones and I think they're still made in America.In fact, I didn't need any of these for myself but bought them for my adult son who just got an air compressor and some air tools. I think the ones I have will probably last longer than me but, if I need a new one for a new tool, I'll buy Milton.

I don't normally write reviews but I thought this product deserved one. I bought this kit and talk about night and day difference from what I had. I went from every connection leaking (and yes I used Teflon tape) to not a single leak anywhere. These are phenomenal. I could feel the difference of the quick coupler the minute I connected them. The best part is not just the quality but the fact that these were just a couple dollars more than what I had. Well worth the buy.

I purchased this and waited a few months to open it (I was waiting on getting a compressor and an air hose). When I did have a need for it I first of all noticed the quality compared to ones I had previously purchased from Harbor Freight. After further investigation the 2-728 plugs were missing! As I was after the 30 days to return the product I messaged Amazon Customer service and they promptly refunded me the money and allowed me to keep the set anyway. I doubt they tried to recover the money from the 3rd party seller, and this is just one more reason I shop at Amazon almost exclusively...love the customer service.As for the couplers I did receive, I replaced one coupler on a air hose that my brother lent me and it instantly stopped leaking. The couplers seal well even when the air hose or device they are connected to are not in perfect alignment and are at weird angles. I'll likely need more couplers in the future when I expand my collection of air tools, and when I do I'll buy these again...but this time I'll open them immediately and check right away that all the pieces are in there!

I had the usual problem of worn, leaky air hose couplers. The ones I have always had were not made in the USA and go figure, generally began leaking soon after purchase. I noticed several reviews mentioned that some big box store brands (foreign made) had six ball bearing construction instead of the standard 3 balls. Milton has three balls. They even worked with the old fittings in my devices. I don't believe the number of balls really equates to quality or proven performance. If three balls have worked all these years for Milton, I'm sold. I think you're asking for trouble having 6.

I can't say enough about these Milton couplers. I have bought the "China Freight" versions for a number of years and have had all the leaky and poor connection problems that come with them after some use. I finally bought this set of made in USA Milton brand air couplers and couldn't be happier. They are a very snug leak-free fit. You will notice the quality as soon as you go to hook and unhook up your hoses and air tools. WELL worth the extra $ and time to switch over from whatever you have now. Wish I had done it sooner.

I bought this set mainly for the S715 couplers. For the price, it ends up being only a couple of bucks more for the 10 extra plugs.It came from Amazon (Seller) in a retail package and made in the USA. I had no issues replacing the leaky Harbor Freight coupler I had bought in a pinch. The HF coupler works but it leaks slightly when the tool/hose is moved around (like using the tool) or in certain positions. The Milton does not leak at all. In fact, all the plugs I have work fine with the Milton coupler so I haven't changed any but I have a mix of HF, Campbell Hausfeld and Milton plugs. They all work great with the Milton coupler.

Milton products are the best you can get. I was raised on a farm and Milton fittings is what we used and never had any trouble. I have tried the cheap air fittings and products, now I'm switching everything out to Milton. The cheap ones leak and don't fit good. Go ahead and pay the difference and get the Milton stuff.
