RoHS compliancy

The majority of the standard products available in the ELESA catalogue are compliant with the European Directive 2002/95/CE (RoHS directive, Restriction on Hazardous Substances).

However, there are some exceptions for some products which are not yet compliant owing to technological limits in the field of research in raw materials hence not due to ELESA's direct responsibility.By clicking on each product code in the table, you can directly check the status of the product as to RoHS compliancy.

All compliant products are supplied with a label showing the RoHS symbol.

Hardened stainless steel ball and stainless steel spring.
- EN 615-L: light end force (marked with one line).
- EN 615-K: normal end force.
- EN 615-KS: heavy end force (marked with two lines).
- EN 615-L/LE: light end force with locking patch (marked with one line).
- EN 615-K/LE: normal end force with locking patch.
- EN 615-KS/LE: heavy end force with locking patch (marked with two lines).
Nylon locking patch for applications subject to vibrations or to eliminate the need for check nuts. Not recommended for applications in soft materials.
Countersink the mating thread at least .030 to .045 larger than the major diameter of the plunger to make insertion of the plunger easier.
