Punched items

made of elastomer and thermoplastics

Product range

We therefore do not provide standard products for standard applications, but specific products which need to be adapted to specific requirements. On the basis of our experience in this area, we would like to offer our extensive services as qualified partner with clean and compatible versions of well-tried and reliable products. Besides specific products, with our laboratory programme and range of sealing items with vulcanised fluorine films (PTFE, FEP, PFA, ETFE) we provide a supply of standardised items which are specified in price lists and stocked generously.

Our products are made of the following materials:

CR Control box seals; protective caps; diaphragms with and without PTFE for oxygen pressure reducers;seal bags; sandwich bearings; expansion bags; lip profiles for bottle turners.
CSM Flap valve seals; acid hoses.
ECO Seals for transformer baking ovens.
EPDM Gaskets for stainless steel screwed pipe-connections; artificial vaginas for insemination equipment; coupler sockets for inhalation devices; reducing rings for drink machines; spacers for heat exchangers, helical hoses for diagnostics units; conical rings for laboratory filters; seal plugs for luminaires; chamber profiles for commercial washing machines, sleeves.
FKM Frames for thermal baths; seals for injection pipes; disc valve seal rings; solvent hoses; conical sleeves.
FMQ Expansion elements for thermostats; carburettor diaphragms.
IIR Blood culture plugs with or without PTFE for test sera; diaphragms for biofermenters; septs.
LSR Catheter brakes; compression seals; sealing rings; plugs.
