Frequently Asked Questions (FAQs)
1. What are the different types of barb fittings?
There are various types of barb fittings available, including crosses, elbows, T connectors, reducing T connectors, straight connectors, reducing connectors, and Y connectors. These fittings come in different materials and configurations, allowing for versatile use in different applications.
2. Are barbed or compression fittings better?
Both barbed and compression fittings have their advantages. Compression fittings are generally more reliable and can handle higher pressures, but they are not as convenient for frequent connection and disconnection. Barbed fittings are easier to connect and disconnect, making them more convenient, but they may not handle as high pressures as compression fittings.
3. How much pressure can a barbed fitting hold?
Barbed fittings are typically used with rubber hose, thermoplastic hose, and certain polyurethane tubing. They can handle a typical operating pressure of up to 150 PSI, depending on the pressure rating of the tubing. Barbed fittings are designed to provide excellent performance and durability over long operational lifespans, with a temperature range of -40ºF to +160ºF.
4. Do you need hose clamps on barbed fittings?
The need for hose clamps on barbed fittings depends on the tubing being used. Tubing with poor memory or that won't relax may not grip well on barbed fittings and may require a clamp for a secure connection. However, if the tubing relaxes between each barb, multiple barbs on fittings can provide additional grip without the need for clamps.
5. How do you size barbed fittings?
Barb fittings are sized based on the inner diameter (I.D.) of the tubing. It is important to match the tube I.D. with the appropriate barbed fitting for a tight seal. On the other hand, push-quick fittings are sized based on the outer diameter (O.D.) of the tubing.
6. What fitting can handle the highest pressure?
Cone and Thread (C&T) fittings are capable of handling very high pressure applications, with some fittings able to handle pressures up to 150,000 PSI. However, these fittings are most commonly used for pressures up to 15,000 PSI.
