Doctor suggested cortisone injection and on July 13 I had a shot in my shoulder. The pain lessened. I had been doing physiotherapy for 9 weeks before and after the shot. However I was at work and had to hop up over a small counter top. My life has been a severe painful nightmare since then. The pain I've been experiencing since that day is unbearable. I was not told that cortisone weakens the tendons in and around the area of the injection. The doctor gives me strong pain killers but they have side effects that I'm looking forward to.
An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
Silicone O-rings Silicone has poor tensile strength, tear resistance and abrasion resistance Silicones possess excellent resistance to temperature extremes. FEP Silicone / Viton Encapsulated O-rings An encapsulated O-ring comprises an elastomer energising core, which has a seamless jacket made from fluoropolymer. HNBR O-rings Hydrogenated nitrile is a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR). KalrezÂ® (FFKM) O-rings This material has outstanding chemical resistance and a temperature capability up to +350Â°C. Ekraz O-rings Ekraz parts have a virtually universal chemical resistance.
