The Male Series 21 Coupling with 1/4" BSP Female Thread is a male quick-release fitting from Delta-P's Series 21 water-fed pole coupling range. Its listed hose-tail or BSP connection is intended for a compatible window-cleaning hose or accessory connection.

Check the precise hose internal diameter or pipe thread before installation, and select the corresponding male or female coupling in the same profile. Not every miniature quick coupling interchanges between different Series 21, Series 26 or pneumatic ranges. Use a suitable sealing and hose-retention method.
