Install Transair Clamshell Fittings in 11 Easy Steps

Install Transair Clamshell Fittings in 11 Easy Steps Transair 6inch Gray Installation Fluid System Connectors DivisionFor proper connection and extra security, Parker Transair uses clamshell fittings for 3" (76mm), 4" (101mm), and 6" (168mm) aluminum pipes. These fittings are ideal for bigger diameters because they eliminate the need for push force (push-to-connect fittings) and hand torquing (snap ring fittings). These fittings can be installed using a battery operated or corded drill, saving time and reducing the chance for personal injury. Clamshell fittings use 4 bolts and a cartridge to make a tight seal between 2 sections of pipe, or a pipe and fitting. As with the rest of the Transair product line, minimal tooling and technical expertise are required for proper installation. 

Clamshell connection technology is the last of the three connection technologies used on Transair aluminum pipe. The use of three different connection technologies ensures that ever diameter is safe, fast, and easy to install. Just like push-to-connect and snap ring, clamshell fittings are rated for compressed air, vacuum, and industrial/inert gases.  

  • Push-to-connect technology is used with 1/2" to 1-1/2" pipe (common applications: airdrops to machines and tools) 
  • Snap ring technology is used with 2" & and 2-1/2" pipe (common applications: compressor outlets and media distribution)
  • Clamshell technology is used with 3" to 6" pipe (common applications: compressor outlets and media distribution)

 

Installing CUT lengths of 3", 4", and 6" Transair Aluminum Pipe in eleven steps

By following these simple steps, you will be an expert installer of Transair clamshell fittings. Cut lengths of 3", 4", and 6" pipe requires you to follow 11 simple steps.

Our video shows you how:

 

 

1. Measure and mark the pipe for cutting

 

2. Cut the pipe

Install Transair Clamshell Fittings in 11 Easy Steps - cut to length - Parker TransairPlace the pipe cutter (EW08 00 03) on the pipe at the desired cutting mark. Rotate the pipe cutter around until the pipe is cut After each full turn, gently tighten the wheel to tighten the cutting wheel. DO NOT use a hack or band saw to cut the pipe

 

 

 

3. Remove debris

4. Lug the pipe

Install Transair Clamshell Fittings in 11 Easy Steps - Create lugs - Parker TransairInsert the appropriate lugging jaws (dependent on size) into the housing on the lugging tool (EW01 00 02). Next, place the jaws around the end of the cut pipe and pull the trigger to create the lug. This process needs to be completed multiple times to get a ring of lugs around the pipe. The suggested number of lugs is dependent on the pipe diameter. (see chart below).

CAUTION: DO NOT overlap the lugs!

 

5. Place the cartridge on the pipe
