When it comes to directing fluid pathways, sealing options are a critical decision to ensuring the containment and operation of your system. From different sizes to different forms of connections, specified tube fittings work to provide reliable linkage to varying directions and containment areas of flow.
What is a Swivel Fitting?
Air Logic swivel fittings, also known as swivel joints, consist of two connection types – threaded and barbed. Each singular part is designed to screw into a female thread on one end and fit in to a variety of tube sizes depending on barb size chosen on the other end. As opposed to a static fitting that remains still and keeps the connections in a fixed position, swivel fittings allow free rotation at the connection point.
The unrestricted movement allows for tubing to twist and rotate without fear of twisting, kinking, or loosening the connection. Due to this feature, the base seals are able to keep their tight seals, whether you use an integrated base or O-ring base seal.
Differences in Types of Swivel Seals
Integrated Base Seal
- An integrated seal bead is embedded directly into the base of the fitting
- No separate O-Ring is needed
- More cost efficient
O-Ring Base Seal
- A separate elastomer ring is placed into a captured groove at the sealing site
- The swivel connection compresses the O-ring against the mating surface to create a higher quality seal
Common Features Across Both Options
Whichever sealing option you decide is best for your application, there are multiple commonalities across the two.
- Tube Connection: Opposite of the thread connections are the barbed connections. The tube’s hoop strength around the barbs ensures a tight hold. Air Logic’s first barb is free of parting lines to enhance this tight hold and sealing capabilities. Tubing ID sizes range from 1/16” to 0.170”.
- Materials: The common materials for the body consist of Nylon, Polypropylene and PVDF, while the elastomer can range from Buna to EDPM (Ethylene Propylene Diene Monomer) to FKM (Fluoroelastomer) to silicone.
- Fitting Shape: While some applications may need just a simple Straight fitting, Air Logic also offers Tee and Elbow fitting to cooperate in the most confined spaces and properly follow avenues for your required fluid flow.
