Ball Joints

Ball joints allow up to 22° of movement off-center and are available in galvanized, aluminum, stainless and stainless+ with optional no. 4 finish.

Construction: 

• Collars: located on the exterior side of each port and considered as air flow non-directional. Collars have a laser welded longitudinal seam (exception: 3" collars are lapped, spot welded, and caulked.)
• If air flow directional product is required, it must be stated on the PO and additional cost may be incurred. A raised lap seam and spot weld are used for attaching the collar to the body and no caulking is used. If caulking is required, additional cost may be incurred.

ORDERING NOTES: Unless specified, 3" through 24" is QF. Over 24" is flanged. Data subject to change without notice. Stainless steel components requiring flanges will be supplied with stainless steel flanges unless otherwise specified. For special parts or items to be custom manufactured, contact us for quotation.
