Push->CONNEX®: By overmolding the Push->CONNEX® utilizing our patented no-parting-line technology, we are able to provide you with the ideal end treatment for insert fittings. Benefits include, no die lines, perfectly round, and registration shoulder, and beveled leading edge to insure no gouging of the o-ring.

Large Elbow Overmold: Our overmold process allows us to put large complex overmolds onto the ends of extrusions.

Overmolded Fill Tube Assembly: By molding a Santoprene fill tube directly onto a polypropylene water tube, we are able to provide a leak-proof joint and a completed assembly.

These CONNEX® overmolded mounting brackets and collars utilizes Merflex? PEX?s excellent creep resistance properties to securely hold the brass inserts, providing a robust metal thread connection point without requiring any additional clamps or mounting hardware.

The patented design of our Slip-Thru nut that can be used with our Quarter-Turn Connection, allows for the nut to be installed onto the tube from the connection end. For instances when the tube must pass through a small hole and the nut is too large to fit, we have designed a side access on the nut to allow easy assembly of the nut onto the tube after the tube has been inserted through the hole. Installing the nut is quick and can easily be done on an assembly line.

Mercury Plastics uses the Connex® overmolding process to combine two or more tubes for the transfer of air, water or other fluids. The finished component provides a one-piece assembly with leak-free connections, fewer SKU?s, easy connections that can be used in hot or cold environments and lower final assembly costs.

Using our CONNEX® overmolding technology, we are able to overmold complicated quick connects onto the ends of tubes with critical internal o-ring sealing surfaces as shown by the large overmold on this part.

This part illustrates Mercury?s ability to overmold an angle outlet with critical external o-ring grooves.

PEX Universal Dishwasher Hook-up: Our patented overmolding process allows us to overmold onto cross-linked polyethylene tubing (PEX). Illustrated here are three details that have been overmolded onto the tube.

Bend-n-Stay: A wire is encased in the Santoprene overmold which allows the polypropylene tube to hold its shape once it is bent. Spin welding is utilized to attach the nozzle assembly to the tube.

Formed Nylon with Quick-Connects: These formed nylon tubes have quick-connects inserted into the ends. Mercury Plastics also has the capabilities to overmold the quick-connects directly onto the tubes.

Braided PEX Overmolded Washing Machine Hose: Any likelihood of water damage is practically eliminated with our braided PEX overmolded washing machine hose. We have replaced the traditional rubber hose with crimped fittings with our braided PEX tubing with the fittings overmolded directly onto the tubing to insure a leak free connection.

Corrugated Hose with Overmold: After extruding the polypropylene corrugated hose, we then overmold the Santoprene coupler. By overmolding the coupler directly onto the tube we reduce the assembly cost and eliminate a potential leak path.

Formed PP Tube with PP Overmolds: This part required us to form the extruded polypropylene tube to fit around other components in the assembly. We have also overmolded directly onto the tube the filled polypropylene quick connects reducing potential leak paths as well as assembly time.

Formed Overmold: In order to provide a 90 degree connection, the PEX tube is overmolded on both ends and then formed.

Quarter Turn Connection: This patented design requires only a quarter of a turn to make a leak free connection. The overmolded male end detail with an o-ring groove is inserted into the female overmolded end. The two ends are locked together by a nylon nut which locks onto tabs that are molded onto the outside radius of the female end. The female tube is also formed to provide easy assembly.

Formed Tube Assembly: To make this tube we extrude the tube, install the foam insulation, overmold the grommet, form the tube, and cross-link the assembly via our electron beam.

Form, Overmold, and Heat Seal: The mounting block is overmolded directly onto the tube, which is then formed and the end heat sealed.

Leak-free Assembly by Overmolding: The injection molded end part is inserted into the tube and then a band is overmolded over the joint to provide a leak-free assembly.

Formed PP Tube with Santoprene Overmolded Ends: The function of this part required us to overmold larger diameter Santoprene tubes onto an extruded polypropylene tube and then form it to shape.

Injection Overmolded Bulb and Nut: Our patented injection overmolding method is used to produce this .312 OD tube with a .250 OD Nut and Bulb connection.

Mercury Plastics patented Push>Connect overmolds have been designed to provide the optimum sealing surface for push-in type fittings. Most leaks associated with push-in fittings are caused by die lines in the tubing or o-rings cut during tube insertion, tubing getting ovalized when cut, out-of-tolerance tubing, or tubing not inserted enough. Our Push>Connect has been designed to solve these problems. The barrel has no parting line and the optimum molded sealing surface. Because the Push>Connect are molded onto the end of the tube, they are perfectly round and are held to tighter tolerance than the extrusion process will allow. The end of the barrel has a beveled edge, so it won?t cut the o-ring and the collar on the part provides an insertion reference point, letting you know when you are fully engaged into the fitting. In addition, we can put a 5/16 OD Push>Connect onto a 1/4 OD tube or mold the ends in any color to aid in Poke-Yoke. All of these benefits add up to a more robust error free connection.

The unique properties of Merflex? PEX makes these three Mercury Plastics designed water connections possible. Because Merflex PEX is cross-linked, it always wants to return back to the shape it was cross-linked in; therefore, it has excellent creep and compression set resistance. This makes it a great material for molding connections. Our Quarter-Turn Connection was designed to be disconnect and re-connected time and time again without failure. It is very intuitive and has a reassuring ?click? to let you know that it is securely closed.

Reducing and improving connections is a specialty of Mercury Plastics. By CONNEX® overmolding onto one end of the tube the body of a push-in type fitting, we have removed one potential leak point of a push-in connector. Also, by molding the push-fitting body directly onto the tube, we have reduced the fitting cost and the assembly cost.
