Rubberexpansionjoint.com WA style molded rubber expansion joints are designed with a molded integral flange and without a metal reinforcing collar molded into the necks of the body. Alternatively, the WA style uses a metal collar cast directly into the retaining ring. The WA style has a much larger arch than traditional spool type rubber expansion joints. This allows for greater movements and lower spring rates when compared to traditional spool type rubber joints. The WA style is also available in a filled arch design know as style WAF. The WA and WAF are a great option for an economical wide arch rubber expansion joint. The WAF style or filled arch will reduce allowable movements by 50%. It will also increase spring rates by 4 times that of the WA style. The filled arch design is a great option to reduce turbulence and eliminates the ability of solids to settle and remain in the arch. The “filler” in the filled arch is made from a soft rubber material that is bonded to the ID of the traditional arch. The ID of the WAF has a one piece seamless inner tube eliminating the ability of the filler to come loose in service.

Remarks:
- The joint body is available in 3 standard combinations of the (tube/cover): EPDM/EPDM, Neoprene/Neoprene, and Butyl/Butyl. The body components (tube/cover) are also available in a combination of the following additional materials on special order: Neoprene, EPDM, Chlorobutyl, Nitrile, Hypalon®, Viton®, Natural Rubber etc. Please see the materials table to determine what material is best for your application.
- Standard flange drilling is ANSI 125/150#. Other drillings available on request.
- Standard flange material is carbon steel that has been treated with a rust inhibitor. Also available T-304, T-316 and other alloys.
- All Movements are non-concurrent. Contact www.rubberexpansionjoint.com to determine if your concurrent movements are acceptable.
- See the “Control Unit” page to determine if your application requires control units. Control units must be used to protect the joint if the piping is not properly anchored. Control units are sold separately from the rubber joint.
Notes:
1. Control unit (3 Rod) Standard
2. Control unit (4 Rod) Standard
3. Maximum working pressure is based on 190° F. See Temperature vs. Pressure chart for operating temperatures above 190° F.
4. Test pressure is 1.5 times working pressure. Burst pressure is approximately 4 times maximum working pressure.
5. The vacuum rating is based on the joint installed in the neutral length. Joints should not be installed in the extended position on vacuum applications. Please advise if the joint will be subjected to full vacuum. The use of an internal vacuum ring may be necessary.
