Simpson Adhesive Piston Plug Flexible Tubing from Simpson Strong-Tie is a purpose-built component of the Piston Plug Delivery System, designed to deliver anchoring adhesive precisely into drilled holes for threaded rod and rebar dowel installations. The tubing connects on one end to the adhesive piston plug and on the other end to an adhesive mixing nozzle, creating a reliable flow path for consistent adhesive placement in overhead, upwardly inclined, and horizontal orientations, as well as deep embedment and submerged (underwater) concrete conditions. Supplied as a single 25-foot roll of flexible plastic tubing, it can be cut to the exact length each installation requires.

Key Features

• 3/8 in. inner diameter and 1/2 in. outer diameter - precisely sized to connect cleanly between the piston plug and adhesive mixing nozzle for a secure, leak-resistant flow path.
• Compatible with all Simpson Strong-Tie piston plug sizes - eliminates the need to source size-specific tubing, so one roll supports a wide range of hole diameters and installation scenarios.
• Works with any Simpson Strong-Tie anchoring adhesive - gives contractors flexibility to switch between adhesive formulations without needing a different delivery tube.
• Flexible plastic construction - allows the tubing to reach awkward or confined anchor points in overhead, inclined, horizontal, and submerged applications where rigid alternatives would be impractical.
• 25-foot roll that can be cut to the desired length - reduces material waste by letting the installer trim exactly what is needed for each drilled hole or embedment depth.

Why This Product

• Built for the most demanding adhesive anchor conditions - from overhead and upwardly inclined holes to deep embedments and fully submerged concrete, this tubing is engineered as part of a system specifically designed for installations where standard dispensing methods fall short.
• Broad system compatibility simplifies procurement - because it fits all Simpson Strong-Tie piston plug sizes and works with any Simpson Strong-Tie anchoring adhesive, a single roll covers an entire project rather than requiring multiple part numbers for different applications.
• Cut-to-length roll maximizes jobsite efficiency - the 25-foot roll lets crews size each piece on the spot, reducing scrap and keeping the installation process moving without pre-cut lengths that may not match the depth of each anchor point.
• Made in the United States and backed by Simpson Strong-Tie system engineering - the tubing is a verified component within a purpose-designed delivery system, giving contractors confidence that every part of the adhesive placement process is engineered to work together.

Frequently Asked Questions

What adhesives is this tubing compatible with?

This flexible tubing works with any Simpson Strong-Tie anchoring adhesive, making it a versatile component within the Simpson Strong-Tie Piston Plug Delivery System.

Which piston plug sizes does this tubing fit?

This tubing is compatible with all Simpson Strong-Tie piston plug sizes, so it can be used across a wide range of hole diameters and installation scenarios without needing to match a specific plug size.

Can the tubing be cut to a shorter length?

Yes. The PPFT25 is supplied as a 25-foot roll specifically so it can be cut to the desired length to suit the requirements of each individual installation.

Is this tubing suitable for underwater or submerged concrete installations?

Yes. The Simpson Strong-Tie Piston Plug Delivery System - and this flexible tubing as part of it - is designed for use in submerged (underwater) concrete conditions, in addition to overhead, upwardly inclined, horizontal, and deep embedment applications.
