More wear resistance, longer service life—PTFE filled with 60%Bronze

After more than 2 years of exploration, DEF Seals developed more wear resistance, longer service life Seals with material PTFE filled with 60% Bronze. This seal looks brighter than the traditional PTFE Bronze seals because it is filled with more bronze powder, so it looks golden.

As we all know, the seal ring is generally used for the hydraulic cylinder. Products like Glyd Ring(Piston Seal), Step Seal(Rod seal), PTFE filled with Bronze Seal, PTFE Spring Seal, Rotary Seal, PU Seal, NBR/FKM/VMQ/HNBR/EPDM O Ring, V-packing Seal, NBR Cotton/FKM Cotton, KDAS Packing, Guide Ring, Wear Strip, polyester Resin seal/tape, PTFE filled with Bronze Tape, Gasket etc… are the commonly used seals or tapes, but how to choose a cost-effective sealing ring is a key factor when we consider the cost of procurement. This material has a longer service life, which greatly saves the use cost of our products to some extent.
Now let’s learn a little bit about the Glad rings.

Size as per Busak+Shamban, Parker, Hallite, and other relative International Standard.
Non Standard products are also available to be made upon your requirement.
