A gasket for use with a connector assembly apt to allow the sealed passage of a fluid through a wall (P) and suitable for installation realized from just one side of the wall, which gasket has a deformable region is provided. The gasket is configured to assume an installation configuration, in which the gasket can be introduced into a connector seat (D) formed in the wall (P), crossing it from side to side, and a sealing configuration, wherein the gasket is installed in the wall (P) and deformed, at the deformable region, to abut on an inside mouthpiece of the connector seat.

A system and method of use thereof to produce pipe connections to conduits which have been remediated using a liner. A pipe clamp is attached after a bore has been made and is secured with a clamping strap, for example. A pipe connection adapter with a flange collar and a seal arranged thereon is introduced from the inside of the pipe. An anti-rotation device between the pipe clamp and the pipe connection adapter ensures that the latter assumes a precisely defined position, such that a flange collar, with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner exactly on the edge of the bore. Connection can also be made from the outside of the conduit.

A threaded fitting comprising a first plurality of threads from a first end of the fitting to a transition thread and a second plurality of threads from the transition thread to a second end of the fitting. The first plurality of threads is configured to provide a labyrinth type seal minimizing the migration of at least dust and/or gases across a thick-walled enclosure. The second plurality of threads is configured to engage a lock-nut in thin-walled enclosures, or a plurality of pre-formed threads within an aperture of thick-walled enclosures, for minimizing the migration of at least fluids/water across one of the thin- or thick-walled enclosure. The first and second plurality of threads are serially-arranged and may be used either thin or thick-walled enclosures to retard a passage of at least one of either gas, fluid, dust and flame.

The invention is a tapping assembly for use on a pipe or tank. It includes a hollow body that sits flush on the outer wall of the pipe or tank and includes a plurality of locking members that sit flush within the body and form a threaded portion into which a cap is inertable. Each locking member extends into the interior of the pipe or tank, and has an outwardly extending flanged portion that engages with the inner sidewall of the pipe or tank. When the cap is tightened against the body, it causes each of the locking member to retract, thereby causing the respective flange portions to lock the assembly against the pipe or tank wall. The assembly can be manufactured to provide either an orthogonal tap, or an angled tap, relative to the longitudinal axis of the pipe, or plane of the tank sidewall.

A device for fixing a nut to an inner surface of a pipe member having a small inner diameter is provided. The device includes a unit box (10) to be inserted into the pipe member, a rotation shaft (11) extending from the unit box (10) to the outside of the pipe member, a cam fixed to the rotation shaft (11) in the unit box (10), and a nut holder (18) that advances from the unit box (10) toward the inner surface of the pipe member by the rotation of the cam. A pressure receiving member to be abutted on the inner surface of the pipe member is provided on an opposite surface of the nut holder (18).

A pneumatic coupler and method for coupling a hose to a surface of an agricultural implement is provided. The pneumatic coupler includes a hollow tube with a radially extending flange. The flange has one or more cutouts to permit the flange to pass through an aperture containing one or more protrusions. The flange has one or more recesses to mate with the one or more protrusions to mitigate rotation of the pneumatic coupler relative to the surface. A nut connects to the hollow tube and at least partially surrounds the hollow tube. A sealing member disposed between the flange and the nut provides a seal at the aperture of the surface.
