Abstract
A two-piece connection between a supply pipe from a source of water and a connection to a fire sprinkler with the connector having a first or rear section entirely above a ceiling and a second or front section connected to the first section with the connection entirely above a ceiling and the forward portion of second section connected to the fire sprinkler. The first connector section, located entirely above a ceiling, has a spherical male sidewall with a rounded leading edge and a rear portion of the second connector section has a spherical female interior surface.
Claims15
A pipe connector comprising:
- (a) a first section including a first interior chamber extending through the first section and a spherical exterior sidewall extending around a front exterior portion of the first section;
- (b) a second section including a second interior chamber extending through the second section, the second interior chamber having a spherical female interior surface leading to a cylindrical interior surface with female interior threads;
- (c) wherein the spherical exterior sidewall of the first section mates with the spherical female interior wall of the second section by a spin weld between the first section and the second section;
- and
- (d) a gasket disposed between a front wall of the first section and the interior surface of the second section.
A pipe connector comprising:
- (a) a first section including at least a spherical exterior rounded sidewall;
- (b) a second section including a spherical rounded female interior surface;
- and
- (c) the spherical exterior rounded sidewall of the first section mated with the spherical rounded female interior surface of the second section by a spherical spin weld between the first section and the second section;
- (d) a gasket located between the first section and the second section.
