McAlpine WC-F21R Straight Flexible Pan Connector with Clamp for BTW Pans

McAlpine WC-F21R Straight Flexible Pan Connector with Clamp for BTW Pans

Features

The McAlpine WC-F21R is a straight flexible pan connector specifically engineered for back-to-wall (BTW) toilet installations. It allows you to make your connections beforehand by tightening the large worm-drive hose clip, ensuring the pan remains securely attached even if you need to maneuver it during final positioning. Furthermore, the soft synthetic rubber inlet accommodates almost all standard pan spigots. Because the outlet is designed to fit directly into 110mm (4″) plain-ended plastic pipe, this connector offers a straightforward, reliable solution for modern bathroom layouts.

• Secure BTW Installation: The integrated worm-drive hose clip locks the connector onto the WC spigot, preventing it from “popping off” during installation.
• Highly Adjustable: You can easily cut this connector to your specific size requirements for a tailored, professional fit.
• Flexible Reach: It provides an effective length ranging from 140mm (closed) to 280mm (extended), giving you excellent maneuverability.
• Hygienic Design: Independent tests prove that the flexible bellows design prevents sediment build-up, maintaining optimal flow efficiency.
• Certified Quality: This genuine McAlpine product is LGA certified and fully complies with DIN 1389:2015-12 standards.

Details

Installing a back-to-wall toilet is often difficult because the connection point remains hidden behind the pan or vanity unit. If the connector slips or disconnects while you push the toilet into its final position, you face the nightmare of removing the entire unit to fix a leak.

The McAlpine WC-F21R removes this uncertainty. By tightening the secure metal clamp onto the spigot first, you create a permanent, vibration-resistant bond. Consequently, you can slide your back-to-wall toilet into position with absolute confidence, knowing the connection will remain solid, airtight, and leak-free.
