What are barb fittings?

Barbed fittings are simple slip-in fittings that can be used with Oval Hose, Polyethylene Mainline Tubing or 1/2" Emitter Tubing. Push the tubing over the end of the barb fitting until it feels snug. At higher pressures (over 20 PSI) use Hose Clamps to secure the tubing onto the barbed fitting.

Keeping this in view, how does a barb fitting work?

A hose barb is defined as one or more continuous ridges or bumps on a fitting that are used to grip the inside diameter of a tube and seal the connection. As a tube is installed on the fitting, it expands over the barb. Grip and seal occur as the tube tries to relax to its original inside diameter behind the barb.

One may also ask, how do you measure barb fittings? Barb fittings are measured by tube I.D. (inner diameter), while push-quick fittings are measured by tube O.D. (outer diameter). If you already have tubing that you are using, be sure to match the tubing to the appropriate fitting for a tight seal.

Besides, what is a barb connector?

A barb connector or hose barb is the section of a fitting or component connected to a piece of hose or tubing by being inserted into that hose or tubing.

How does an fitting work?

AN fittings feature a special 37 degree flare to create a metal to metal seal when they are connected, and are NOT the same as flare fittings you find at the hardware store. Those fittings have a 45 degree flare and WILL NOT WORK WITH AN! Don't use hardware store parts to plumb your next project!

What is a hose size?

Hose diameters range from 3/8 inch, 1/2 inch to 3/4 inch. In the United States, most standard garden hoses are 5/8 inch in diameter. The bigger the diameter, the more water is delivered.

How do you measure a hose barb?

Hose barbs are sized by the tubing ID (inner diameter). So, the hose barb itself is going to be larger in diameter than the inner diameter of the hose. And that's what we're sizing for-- the inner diameter, the hose. For example, a 3/8 hose barb is 3/8 tubing ID.

How do you measure a hose fitting?

Measure the Outside Diameter (OD) of your pipe or pipe fitting:
  1. Wrap a string around the pipe.
  2. Mark the point where the string touches together.
  3. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
  4. Divide the circumference by 3.14159.

How much psi can a compression fitting hold?

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.

What is tubing used for?

A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires. The terms "pipe" and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe.

How much pressure can a barbed fitting hold?

Typical working pressure for hose barbs is 150 PSI. However it is important to note the pressure rating of the hose or tubing being used. Polyconn always recommends the use of hose clamps or other retention devices to secure the hose to the barb fitting.

What is hose ID?

Inner diameter (I.D.) is the span of the empty space in a circular hose cross section that affects the flow velocity of the fluid within the hose. A hose with an oversized I.D. will result in sluggish system performance, while an undersized I.D. can cause excessive pressure drops, leaks, and system damage.

How do you install a poly pipe fitting?

How to Install Poly Pipe Fittings
  1. Cut the required length of tubing from a polyethylene pipe roll with a sharp-bladed utility knife.
  2. Dip one end of a barbed poly fitting in a water-based lubricant.
  3. Forcefully push the fitting into the end of the tubing as you twist the fitting back and forth.

How do you remove a barbed fitting?

Soak the tubing in scalding hot water. If the tubing is in an area where the use of water isn't possible, heat the hose with a hair dryer. Twist the tubing back and forth until it pulls off of the barbed fitting. The heat will help expand and soften the tubing until it can be pulled off the barbs.

How do you soften plastic tubes?

Immerse the coiled tubing into the water. Turn the burner on high to allow the water to boil. Boil the tubing in the water for five to 10 minutes. The heat will soften the tubing, allowing you to reshape it into a long, straight line.

Can you use PEX fittings on poly pipe?

If you are working with PVC or Polybutylene Pipe and need a way to quickly transition to PEX, Copper, C-PVC, PE-RT or HDPE pipe, we have you covered. SharkBite fittings can quickly transition from one pipe material to another. SharkBite fittings with a gray collar are compatible with polybutylene pipe.
