The present invention is to provide a boring machine capable of easily controlling a proceeding speed of a cutter by manual rotatable operation of a handle. In a boring machine 5 for boring a part of a fluid pipe 1 in an uninterrupted flow state, including: a shaft member 54 having a leading end to which a cutter 52 is attached; a drive means 55 configured to rotate the cutter 52 and the shaft member 54 around the shaft of the shaft member 54; and a forward and backward moving operation means 56 configured to move the cutter 52 and the shaft member 54 forward and backward in the axial direction of the shaft member 54 by a handle 56a that is manually rotated. The forward and backward moving operation means 56 is further configured to switch a feed amount of the cutter 52 and the shaft member 54 in the axial direction between at least two different feed amounts according to a rotational amount of the handle 56a.

A pipe connector for connecting two pipes is provided. In the pipe connector, a projection ring is circumferentially formed on an inner circumference of a rubber sleeve at a position, which is spaced a distance from one inlet of the pipe connector, such that a connection end of the pipe inserted into the pipe connector comes into contact with and is held by the projection ring. The casing and an auxiliary casing are provided, on opposite ends thereof, with stopper bends, a width of which is as much as 1.2~2 times a thickness of a grip ring.

A block fitting (100) for an air conditioning system includes a male block portion (106) and a female block portion (108). The male block portion has a first annular pilot (126). The female block portion has a first annular collar (155) that receives the first annular pilot of the male block portion. The first aperture of the male block portion and the first aperture of the female block portion are substantially concentrically aligned. A first seal structure (102) is disposed between the first annular pilot of the male block portion and the first annular collar of the female block portion. A fastener (120) engages the male block portion with the female block portion to form a substantially fluid tight seal. One of the of the male block portion and the female block portion has a stabilizing heel (156) formed adjacent a side surface thereof. The stabilizing heel (156) militates against transverse dynamic loading of the seal structure in operation.
