About this deal

These tried and tested compression fittings remain the preferred jointed technique for many domestic installers due to their exceptionally high quality. Fittings are also compatible with connecting low carbon steel, stainless steel and many types of plastic pipe including crossed linked polyethylene (PE-X) and polybutylene (PB) with size compatible outside diameters. There is no significant difference. Compression fittings designed for liquid will work fine with gas but if you use optional PTFE tape, make sure it is gas grade. In addition, ensure the fittings are accessible and not hidden behind walls or under floors. Are Compression Fittings Reliable? The traditional ways to connect copper pipes are with capillary joints that you need to solder, and brass compression joints that you tighten with an adjustable spanner. However, plastic push-fit joints are just as effective - and much simpler to use. They come with rubber O-rings for sealing, and work well with both plastic and copper pipes. Safety first Metric and imperial measurements of the fittings provide inner and outer diameter. Metric measurements

Plastic push-fit joints on copper pipes break the continuity of a plumbing system's earth bonding. You must restore this by joining the two copper pipes with a length of 4mm2 single-core earth cable, secured by earth clamps. Capillary joints Some fittings on the market use only a number to mark the size without using the unit next to it. Since the imperial way of marking the fittings is getting less and less popular these days, its really easy to differentiate the fittings by using just 12, 14, and 16 as the size differentiators.

Stainless steel compression fittings in all sizes

We would wrap up this article at this moment, although we are certain that we didn’t cover all the small details. As we said at the start, this subject is very broad, there are many choices, but we hope that we managed to cover the basics. In one of the future articles, we will cover the subject of angled adaptersand other special connectors, such as T-Splitters and Ball Valves! Compression fittings are especially advantageous in retrofit plumbing schemes, where the use of heat must be avoided. They are available in 8mm – 54mm and are suitable for connecting tubes in accordance with EN 1057 and many other standards. The liquid cooling market provides three diameters of soft tubing that are the most common. Tubes are marked with ID and OD which stand for „Inner Diameter“ and „Outer Diameter“. There are two ways to mark the fittings, one is using metric millimeters (mm) and the other is using imperial inches (“). These three most common tubes are marked with numbers such as:

Soft tubing is often made out of neoprene, rubber, silicone, PVC, or other special compounds that are specifically made to be compatible with PC liquid cooling. You can choose see-through – clear tubing, colored – non-transparent tubing, and UV reactive tubing. You cannot choose any tubing from the local market for water cooling. Well, ideally, you can, but no one can guarantee if some manufacturing residues will impact the coolant stability, or you will spring a leak because of size tolerance issues. These compression fittings are marked with two numbers that state the inner diameter (ID) and outer diameter (OD) of the tubing that is compatible with the fitting. Both these number markings of the tubing must match with the fitting. As for the old-school barb fittings, there is only one number present, the OD of the barb, which has to match with the ID of the tubing that will be used. Thankfully, both the tubing and fitting types are standardized, so you are able to choose from 10/13, 10/16, and 12/16 sizes of soft tubing compression fittings. These fittings are advantageous if you’re familiar with using compression fittings. Because they’re typically used in low-pressure systems and tend not to require a user to do any soldering/welding, they’re suitable for domestic use.The other, less common hard tubes can be made out of copper, brass, borosilicate glass and nowadays even carbon tubes are coming into fashion. The potential problem with these materials is that bending them is not possible or bending requires special tools. We say the „potential problem“ because skilled and more advanced users actually prefer these luxurious materials because the loop can still be connected just by using more adapter fittings and more joints.

While in the early days we had simple barb fittings, nowadays the market has narrowed down to only compression type fittings. While barb fittings are still available for workstation purposes and applications where the aesthetics are not a key point, the market is dominated by compression type fittings. The compression fittings themselves are divide into two major categories which are, Soft Tubing Compression and Hard Tubing Compression fittings, or for short STC and HDC. Soft Tubing Compression Fittings Moving onto the other type of tubing, called hard tubing. Unlike the soft tubing, that is made of some sort of synthetic rubber or plastic, hard tubes can be made from a broad spectrum of materials. The most common hard tubes for liquid cooling are acrylic (plexiglass) or PETG (polyethylene terephthalate). They are cheap, easy to come by, and can be shaped and bent in every household. There are tools available which can make acrylic and PETG bending really easy, but we will not elaborate on that subject now, we will leave that for another article as hard tube bending is considered to be a more advanced loop building method. Regarding the fittings, there is one more detail you need to know. Almost all of the fittings nowadays use the G1/4“ thread (12.9mm wide) and this is the industry standard for all mainstream custom loop liquid cooling manufacturers. In case you are tumbling through server solutions or some older water cooling gear, you might stumble upon G1/8“ (9mm wide) or G3/8“ (16.5mm wide) threads. But like we said, the G1/4“ is the norm and the other sizes have become very rare. So the G1/4″ label is just the thread size label, which makes sure that your liquid cooling products are compatible with each other. If you are welding or adapting a system, you may want to opt for brass fittings instead. Are stainless steel compression fittings ok for domestic use? At Plumb Parts our range of compression fittings are suitable for a broad spectrum of applications across the domestic, industrial and commercial sectors.Compression fittings are tested and approved, for use with drinking water up to 108mm and for gas applications up to 28mm.
