U-BEND FITTING
First Claim
1. A U-bend fitting for connecting a first pipe and a second pipe, wherein the first pipe extends substantially parallel to the second pipe, the U-bend fitting comprising:
- a first collar having an inner surface and an outer surface, the first collar configured for connecting the first pipe to the U-bend fitting;
a second collar having an inner surface and an outer surface, the second collar configured for connecting the second pipe to the U-bend fitting;
a curved hollow body having an inner surface and an outer surface, the curved hollow body extending from the first collar to the second collar;
a flow path formed by the inner surfaces of the first collar, the curved hollow body, and the second collar, the flow path configured to allow fluid to flow from the first pipe to the second pipe; and
a brace extending transversely between the outer surface of the first collar and the outer surface of the second collar, the brace configured to resist movement of the first collar toward the second collar that would bend the curved hollow body.

Abstract
A U-bend fitting for connecting a first pipe and a second pipe, e.g., in cooling pipe system for an ice rink, is disclosed. The U-bend fitting includes a first collar, a second collar, and a curved hollow body forming a fluid path configured to allow fluid to flow from the first pipe to the second pipe. In one embodiment, the U-bend fitting includes a brace extending transversely between the first collar and the second collar, the brace configured to resist movement of the first collar toward the second collar. In another embodiment, the U-bend fitting includes a concave channel extending longitudinally along at least a portion of the outer surface of the curved hollow body. The concave channel is configured for receiving a curved surface of a support to which the outer surface of the curved hollow body can be tied.
