End Caps

Stoppers (end caps) can be used to temporarily or permanently seal pipe openings during tightness tests.

• For nominal sizes DN 100 to DN 200, the stopper is inserted into vitrified clay pipe sockets with socket type L (joint system F).
• For DN 200 to DN 300, the stopper fits sockets with joint type K (joint system C).

Vitrified clay pipes and fittings are standardized according to EN 295-1. Additional requirements are covered by the certification program ZP WN 295.

Important: All dimensions—especially when connecting to other components—must be verified based on EN 295 and ZP WN 295. Technical specifications are subject to change.
