The standard material is Polyamide (Nylon) which is resistant to various chemical products, has excellent mechanical properties including wear resistance, low friction coefficient, high melting point and good impact resistance and is also very light. The working temperature range is -30 to +100°C.

Other materials are available on request, such as PP, PE and POM (these materials are recommended for their good food and medical qualities) or PA glass filled (tensile strength and high rigidity - it ideally replaces aluminium and zinc in tap parts).

The knurled thumb screws are available in M5, M6 and M8 (Length from 6 to 60mm).

The standard colour is natural but we can supply these parts in a wide range of colours to suit your requirements.
