摘要： A fitting to interconnect water pipes or to connect pipes with valves or mountings. The connector housing has an O-ring seat, constituting two walls of a groove for an O-ring. The fitting comprises a clamping sleeve, having a first end provided with a flange, which forms a third wall of the O-ring seat groove. The flange is retained against the coupling housing by a nut screwed by hand onto outer threads on the coupling housing. The clamping sleeve is adapted to be clamped against a pipe which is inserted into the clamping sleeve, and the O-ring seals against the outer surface of the pipe.

摘要： A method for manufacturing a resin pipe joint with a joint body includes the following steps. Preparing a mold and a supply device configured to supply molten resin. The mold includes a first mold for an outer shape of the joint body and a second mold for an inner shape of the joint body. Combining the second mold with the first mold to form a cavity, into which the molten resin is injectable, inside the mold. Supplying the molten resin to the cavity in the mold. Solidifying the molten resin in the cavity after stop of the supply of the molten resin from the supply device. The second mold has a gap that connects the cavity to a discharge space outside the cavity and allows gas to flow.

摘要： A sealing ring for sealing in a pipe joint an annular space between a socket end and a spigot end introduced therein comprises an annular sealing portion (8) consisting of elastically yielding sealing material and a substantially annular reinforcing portion (10) consisting of a material which is rigid in relation to the elastically yieldable material, the sealing portion (8) and the reinforcing portion (10) being fixedly connected with each other at the connection surface (18). The outer surface (40) of the sealing ring has a surface portion which is of a shape corresponding to the shape of the connection portion as parallelly displaced in the axial direction of the ring. The invention also relates to a mould for manufacturing such a sealing ring by means of injection moulding.

摘要： Reinforced sealing ring for reception in a pipe joint between an annular groove-carrying socket end and an insert end. The sealing ring consists of a main body of rubber in which there is embedded an upsplit steel ring. The sealing ring is adapted to be elastically deformable to such a degree that it can be snapped into place in the annular groove of the socket end by a simple mounting operation while it can be prevented from being torn or pressed unintentionally outwards from the annular groove after mounting. In order to achieve this the main body has a largest external diameter of between 1.08D+16 mm and 1.04D+8 mm, while the cross-sectional diameter or thickness of the steel ring is between 0.01D+2 mm and 0.005D+1 mm, where D constitutes the diameter of the pipe. The steel ring is disposed embedded in a central and/or radially outer cross-sectional portion of the main body.

摘要： Combined mould and sealing element suitable for sealing off a joint between a socket end and an insert end of two cooperating pipes formed from a thermoplastic material and for being used as a portion of a body of a mould for both fabricating said socket end of the one pipe and simultaneously inserting said element in an internal groove in the socket end produced thereby. The element consists of a main body of annular form composed of an elastically yielding material housing a reinforcing core of relatively non-elastic material capable of retaining its shape relative to the main body. The main body has a radial outer portion which in its active condition is adapted to abut the bottom of the internal groove and in its inactive condition projects outwardly as a flap. Between the flap and an inner and opposing portion of the main body there is formed an opening dimensioned to facilitate ready introduction and housing of the core. The flap has a wall thickness which is locally reduced at a position remote from its free end which permits ready bending and clamping of the flap against the inner portion to close off the opening in the active condition.
