Main Rubber Supply can supply custom or stock rubber extrusions in a wide variety of profiles. Sometimes we have stock molds or dies to produce the parts but in cases the tooling charges for new custom shapes are extra. If your part already exists please send us a drawing or sample for us to quote. If you are in the design stage, contact us for a custom quote.
We can supply P seals in various bulb diameters, solid bulbs, tail lengths and compounds. A typical application is for a rear door seal on solid waste trucks. The bulb portion of the seal compresses when the rear door is closed sealing off any waste fluids and when the door is opened for loading the bulb returns to its original size. The tail portion of the seal is where it is mechanically fastened to the door frame.
These profiles are supplied for many industries but a popular is the aggregate industry where U channels called bucker strip or screen protector rubber is attached to heavy metal screens in the crushing and classifying of rock by size. These rubber u channels protect the metal screens and reduce noise. Other uses are for sheet metal edges as protectors against cutting.
Wedge profiles have been made in many sizes but a typical application for wedges are to block large paper rolls in paper mills and to block large steel coils in steel plants and steel processing centers. Typical size would be 3 ½” high and 5 ¾” deep x approximate 10 foot lengths.
