For option (C) Bloxwich fit Oilite® sintered bronze bushes. Oilite® is the undisputed market leader in self-lubricating bearings and the properties of the standard Oilite® oil retaining tin bronze give a good balance between strength, wear resistance, conformability and durability in operation. They are ideal in a wide variety of applications where "self-lubricating" properties are required over a long period of time.

Depending upon the design it can be impossible to weld the area between the back of the hinge and the face of the door if using J seals. Bloxwich "Seal-Groove" hinges:

-Allows sealant to be applied forming a barrier across unwelded part of hinge.
-Prevents corrosion by stopping ingress of water behind hinge.
-Sealant easily applied by conventional sealant gun.
-Prevents rust streaks (as found with conventional hinges ) from forming on doors.
-Seal-groove provides visual proof that the hinge has been sealed over total width.
