These o-rings are a great deal. I purchased them to repair brass hose nozzles when they stop working, and they work great. Not only can I repair many hose nozzles, but the 2 kits also come with every size imaginable, SAE and metric, for repairs of any future projects that might require a new o-ring. I would give this 6 stars if I

This is a great assortment of o-rings. Well organize compact design. Both metric ID 3mm to 50 mm and standard sizes ID1/8 to 2 inch 10 of each size....standard in red box metric in blue. Box is 10"x6"x1.5 inches. Smaller sizes in lid are stores on stored on spokes with flanges to hold the in place and are desgned to nest inside lager

O-rings are taken for granted, but they're actually a crucial piece of precision engineering. O-ring grooves are actually carefully engineered for correct compression of the O-ring to provide sealing. Thousandths of an inch make the difference between a good seal and an eventual leak. This is why O-ring grooves are designed to fit

I needed some pneumatic tubing for the drain line on my refrigerated air dryer. I’ve worked in the building and process automation fields, for many years, and know that it’s worth paying for good quality pneumatic tubing. Especially, if it’s going to be exposed to cold temperatures. This isn’t the least expensive tubing that

I bought the 1" Barb x 3/4" Male Pipe fitting to replace the steel pipe setup from the well that always rusts and leaks due to the very acidic water in the area. This is a very heavy duty brass fitting with a thick wall. The barb is big enough for two pipe clamps and fits securely in the black pipe coming from the well. It

I needed these for a domestic water line. They are not lead free, so technically they shouldn't be used for that purpose.

This adapter definitely not a Pro-grade adapter:- the quality of NPT thread is not perfect,- the thickness of barbed fitting is not enough in comparison with the Pro-grade adapters,- the barbed fitting is extremely short (just 4 barbs) in comparison with the Pro-grade adapters (7,9,11 barbs). That means there is no room to install two or

I typically always read the 1 star reviews first. You really need to be subjective to the item and the person. Some folks are "internet experts" and some have a "working knowledge". There were reviews about how the thread end was not tapered. Its visibly tapered and worked as it should. That myth has been debunked.... I used some

First off, these are not NPT compliant. (National Pipe Thread, the standard used in the United States). There is no taper whatsoever, the diameter is the same the entire length of the thread, which will cause the fitting to leak. Brass fittings are intended to deform and thus create a tighter connection, which is absolutely vital if you

These pneumatic fittings work perfectly fine. The people that are having troubles, I believe, don't really know what they are doing. I have been building industrial equipment and using components such as these for more than 35 years. These work as fine as any other brand of fitting of this type. The tubing must be cut square.

Like these but the pre applied teflon pipe dope is like cement. I got 1 thread of engagement before I didn't feel comfortable applying more torque. Soaked dope in acetone for an hour which loosened it up. Hit it with a small flat blade screwdriver to take off the first layer and soaked for another hour. Rest came off with a brass brush.

The check valve failed on my Central Pneumatic 29-gallon compressor.

Great for my projects! I’m prototyping a few microcontroller projects that involve positive and negative / vacuum pressure. The quick connects were a really nice surprise.

The slightly undersized dimension of the hose can cause problems with push fittings developing slow leaks, especially if there is any sideward "pressure" on the hose right at the junction where it enters the fitting. If you have to force the hose to be straight at the point where it inserts into a push fitting, once it's inserted

PU tubing is great, easy to work with and pliable but sturdy. My issue is that several of the fittings are leaking. Enough that it cycles the compressor in standby over a period of about 90 minutes. Not a big deal, but I have seen better quality. The brass fittings are the worst, but I have one push fitting elbow that is also leaking.

I really like that you feel the two-step connection when you push the hose or tube into the fitting The release ring is oversized making it easy to remove a fitting but it’s firm so that you’re not worried about accidentally loosening the fitting during installation When you’re moving everything around i’ve used him for 150 psi

I really like the ease and quality of this product.These are really nice connectors. If they leak, the tubing is probably not pushed in all the way. When you push the tubing into the connector, you have to make sure to push them past the second point of resistance. I believe the first thing you feel that might be confusing is the prongs

This product has a reasonable price, is said be stainless steel, and is serving it's purpose. However, the threads (particularly the inner threads) are of poor quality.

It's not just that the threads aren't cut all the way through, as another reviewer mentioned - that normally wouldn't be a problem if the threads were cut at the right size. But the inner threads are cut too big. Does not fit standard ½" NPT. Both ends of the threads hit the end of the threads before they get tight. Can't believe
