A hot tapping drill apparatus comprising a housing, a rotation shaft arranged within the housing and comprising at least two secondary rotation shafts telescopically arranged and keyed to allow transmission of torque, one end of the rotation shaft extending outside the housing and configured to operatively receive a drill bit, in use. The drill apparatus also includes a translation shaft arranged within the housing and comprising at least two secondary translation shafts telescopically arranged via a complementary threaded engagement to allow for telescopic translation of the secondary translation shafts due to relative threaded rotation. Also included is a link assembly linking the rotation and translation shafts to allow independent rotation of the rotation shaft while coupling translation of both shafts.

A pipe fitting placement system includes a fitting holder including a bar defining a fitting bore proximate to a first end of the bar, the bar further defining a second end distal from the first end, the bar being elongated in a longitudinal direction extending from the first end to the second end; and a saddle coupled to the bar proximate to the second end of the bar, the saddle rotatable about a saddle pivot axis with respect to the bar; and a pipe fitting received within the fitting bore of the fitting holder.

The present disclosure provides a fluid introducer for a piping system that includes first and second piping sections. The fluid introducer provides a direct connection to the first piping section through a separator body configured to be positioned in an expansion gap between the first piping section and the second piping section such that a first end face of the separator body faces the first piping section and a second end face of the separator body faces the second piping section. The fluid introducer is configured to direct fluid from the fluid source through fluid introduction passaging into the first piping section and block the fluid from flowing into the second piping section.

An irrigation emission device includes a barb that is self-piercing, and the irrigation emission device may be installed either manually or with the use of a piercing or insertion tool. In any event, the barb assists in making installation easier by piercing the hose to insert a portion of the device through the hose. Preferably, the barb will not pierce an opposing wall of the hose during installation.

A fitting for a pipe generally includes a saddle for coupling the fitting to the pipe and a tap for establishing fluid communication between the fitting and the pipe. The saddle defines a channel extending generally longitudinally through the saddle, and the channel is free of threads. And, the tap is configured to fit within the channel of the saddle for establishing the fluid communication between the fitting and the pipe.
