Frequently asked questions

Why polyamide and not steel?

Polyamide gives significantly lower weight (45-104 g vs 250-1100 g for steel MB). This is an advantage in transport installations where weight is critical.

For which couplings?

TW MK coupling (SKU 5572) and clamping ring MKV (crown ring SKU 5581). Note that MB (5576) is for VK coupling - not MK.
