The function of a 45 degree elbow is same as a 90 degree elbow, but the measurement of dimensions is different as compared to that of 90 degree elbow. The radius of a 45 degree elbow is the same as the radius of the 90 degree L.R. elbow where 'R' equals 1½ D. However, the center to face dimension is not equivalent the radius as in 90 degree L.R. elbows. This is measured from each face to the point of intersection of the center lines that are perpendicular to each other. This is due to the smaller degree of bend.
45 degree elbow, also called "45 bends or 45 ells" are mostly made as LR (Long Radius) elbows. Available in various sizes (in mm or inches), 45 degree pipe elbow is available with different male to female BSP thread connections. Providing a wide choice of colors, these elbows can be manufactured to meet different requirements, in terms of size and diameter. They can be made from different materials like silicone, 3 ply material etc and both long and short radius elbows are available in the market.
