Special eye forms for extension springs: There is an increasing number of potential applications for trumpet-end springs and mounting aids for extension springs – a solution that we have been addressing for many years now. We produce our range of extension springs with German and British standard eyes with wire diameters of 0.25 mm to 4.00 mm. We can also produce special-purpose eyes and other eye forms as needed according to alternative specifications with wire diameters of 0.20 to 4.00 mm.

Our assortment of threaded screw fittings ranges from connectors, double threaded nipples, counter nuts and bushings to reducing nipples, pipe double nipples, hose sleeves and pivoting bushings and up to bulkhead fittings, union nuts, extension pieces, end caps and locking screws. We also offer various fittings made of steel and malleable cast iron as well as assortment boxes with a chosen selection of screw fittings.

This thermocouple extension can be used for any thermocouple with type “K” mini plugs. Selecting these high-grade components achieves long service lives.
