Product Overview
The Fernco QwikFlex Pipe Connection Kit is engineered for ease of use and reliable performance in DWV applications. It eliminates the need for primers, glues, or special tools, simplifying pipe connections.
Key Features:
- Pipe Connector Kit: Designed for connecting drain, waste, and vent pipes and fittings in hard-to-reach areas or to join misaligned pipes.
- Easy Installation: Simply measure, cut, and fasten. No need for odorful primers, glues, or a slew of fittings. No special tools needed.
- Reliable Connection: Creates strong, leak-proof pipe joints up to 24-inches in length. Backed by over five decades of proven performance.
- Kit Components: Includes two 12-inch long flexible couplings, one 45-Degree Connector, and one Straight Connector.
- Specifications: Large hubs connect to 1-1/2" SCH40 PVC pipe. Made in the USA. Meets ASTM C1173 Standard. QwikFlex couplings can flex for up to 20-degree offsets.

Important: This product is specifically designed for Drain, Waste, and Vent (DWV) applications only. It is NOT suitable for pressure applications. Ensure the system pressure does not exceed 4.3 PSI.
Always consult local codes and authorities prior to installation to ensure compliance with all applicable regulations.
Setup and Installation
The QwikFlex Pipe Connector Kit is designed for straightforward installation. Follow these steps for a secure and leak-proof connection.
Installation Steps:
- Prepare the Couplings: Tighten all bands on the QwikFlex couplings to 60 inch-pounds before installation.
- Measure and Cut: Measure the required length for your connection. QwikFlex couplings can be cut to length as needed. Ensure clean, straight cuts.
- Align and Insert: Align the QwikFlex couplings to determine where to cut. Insert the cut coupling into the existing pipes or fittings.
- Fasten Connections: Insert the cut coupling into the QwikFlex couplings and tighten the bands to 60 inch-pounds.
- Test for Leaks: After installation, thoroughly test the system for any leaks.
Note: Straight and 45-degree connectors increase versatility. QwikFlex components are not intended to support other pipe or fittings; support and brace the assembly as well as the pipe and fittings they are connected to.
Do not over-flex the QwikFlex couplings, as this could cause them to kink and create an obstruction.

Operating Principles
Once properly installed, the Fernco QwikFlex Pipe Connector Kit provides a durable and flexible connection for DWV systems. Its elastomeric polyvinyl chloride (PVC) construction ensures resilience against soil conditions, and it is designed to be leak-proof and root-proof.
The flexible nature of the couplings allows for joining pipes with minor misalignments, up to 20-degree offsets, making it ideal for challenging installations where rigid fittings may not suffice.
Maintenance
The Fernco QwikFlex Pipe Connector Kit is designed for long-lasting, maintenance-free performance once installed correctly.
- Periodic Inspection: Periodically inspect the connections for any signs of leaks or damage, especially if the system experiences significant temperature fluctuations or ground movement.
- Cleaning: The exterior of the couplings can be cleaned with mild soap and water if necessary. Avoid harsh chemicals that could degrade the PVC material.
- Environmental Factors: The PVC material is unaffected by typical soil conditions, but ensure the surrounding area remains free of sharp objects or excessive external pressure that could compromise the pipe.
