8mm compression fitting

The most common sizes for hard tubing compression fittings are for 12mm, 14mm and 16mm tubes.

Are there metric compression fittings?

Metric compression fittings are available in steel, stainless steel, and brass, depending upon the tubing material that is being used.

How many PSI is a compression fitting good for?

Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10,000 psig.

Are NPT and compression the same?

NPT or IPT pipe threads are tapered, Compression Fitting Threads are Parallel.

How tight does a compression fitting need to be?

Compression fittings should be tight enough to create a watertight seal but not so tight that the pipe warps or the thread is damaged as this could encourage leaks and make the fittings much harder to remove later. Proceed with caution.

What happens if you over tighten a compression fitting?

Its often said in the trade to not over tighten a compression fitting, leaving you more thread in the case of a leak and not distorting the olive or fitting. Generally a nut will need one whole turn after hand tightening.

Are there metric hydraulic fittings?

We offer a full selection of Metric Hydraulic Adapters and Fittings, including BSPP, BSPT, Metric, and 30° Seat. Tompkins metric compression fittings are highly resistant to vibration and create strong, reliable, leak-free connections. They meet or exceed all SAE, ISO and DIN standards.

What is metric hydraulic fitting?

Home /Metric DIN Hydraulic Fittings. A metric DIN fitting is a compression-style fitting with a flareless bite type construction used to connect Metric tubing to fitting thread connections. They're composed of a body, ferrule, and nut.

Do compression fittings need gaskets?

Unlike other types of joints, compression fittings do not need additional sealing materials like gaskets or o-rings because they seal through the use of threads alone.

What is the most common cause of leaking compression fitting?

If the nut is overtightened the ferrule will deform improperly causing the joint to fail. Indeed, overtightening is the most common cause of leaks in compression fittings.

Do compression fittings fail?

Unlike threaded fittings, compression fittings can seal properly but nevertheless slip out of position as a result of forces on a pipe. In this case, the plumbers failed to properly restrain the repaired pipe when using compression fittings.

Do you use pipe thread on compression fittings?

Used very commonly with with copper to connect copper tubing it's it's all you also use that as you

What type of threads do compression fittings use?

Compression fittings have straight threads and are made of brass or plastic and are often used on soft copper pipe and small-diameter tubing. The angle stop under your sink is one example of compression threads.

What size compression fitting do I need for 1/2 inch pipe?

Compression fittings are sized according to that outside diameter: a 1/2" OD pipe would require a 1/2" compression fitting.

Should I use PTFE tape on compression fittings?

Can I Use PTFE Tape on Compression Fittings? No. PTFE tape is not designed to seal compression fittings and is ineffective at doing so.

How do I stop my compression fitting from leaking?

Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe (Photo 3). Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak. If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn.

Are compression fittings as good as solder?

Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.

Do compression fittings leak at first?

They are often used to connect fixtures and appliances that will eventually need to be replaced. While compression fittings are convenient, they may leak if not installed correctly. If a leak does develop, there are steps you can take to fix it.

How do you use PTFE tape on compression fittings?

There is a right way and a wrong way to use PTFE tape. The right way is to wrap it clockwise around the thread of the joint. The easiest way to remember which way to wind the tape is to hold the pipe in your left hand and apply the tape with your right hand.

Can I use brass olives on copper pipe?

Olives are ideally suitable for use with compression joints and copper or plastic pipe. Supplied in either copper or brass the olive fits directly to the intended connecting end of the pipe.
