The H-2NP is a anti-static metal single joint that is also part of the formation of multiple steel connectors, namely HJ-2NP, HJ-3NP, and HJ-5NP. This joint is one of the most versatile of the Flexpipe system. Since it is needed to create three connectors, you should always keep a box of H-2NP in stock.
This single joint has up to four internal striations for a better, stronger grip on the 28mm pipe's coating. It was also manufactured with four pre-drilled holes for reinforcement when building heavy-duty structures.
