Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. It was invented in November 1978 [2] and brought to market in the early 1980s by part of Imperial Chemical Industries (ICI), the PEEK division was acquired through a management buyout, giving rise to Victrex PLC.

In events in which there are cuts, only golfers who make the cut for an event will receive points for that event. In case of a tie, point totals are added together and divided among all golfers tied for a particular position at the end of a tournament.
A 37° flare type end fitting for flexible hose. The AN thread (also A-N) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN.
Swiss Fittings is legally protected the German Brand "Pressfittings aus Edelstahl" in the USA. [32] Press fittings of some major brands carry a plastic slip [clarification needed] around the sleeves on each end of the fitting which falls off when the fitting has been compressed. This allows for a simple identification whether a press fitting ...
American National Standard Pipe Thread standards, often called national pipe thread standards for short, are United States national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes, including rigidity, pressure-tight sealing, or both. [1]
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.
