Simpson Adhesive Piston Plugs 1 inch are precision-fit plastic plugs from Simpson designed to work with the Simpson Strong-Tie Piston Plug Delivery System for dispensing anchoring adhesive into drilled holes. The matched tolerance design between the piston plug and the drilled hole virtually eliminates the formation of voids and air pockets during adhesive dispensing, supporting consistent bond quality along the full embedment depth. A barbed end provides a reliable connection to the flexible extension tubing, and the model number is embossed directly on each plug for quick, on-site identification.

Key Features

• Matched tolerance design sized for 1 in. drilled holes - the precise fit between plug and hole virtually eliminates voids and air pockets, so adhesive is distributed consistently throughout the embedment depth for dependable bond quality.
• Barbed end connection - provides a reliable, secure attachment to flexible extension tubing, reducing the risk of disconnection during dispensing in difficult orientations.
• Works with any Simpson Strong-Tie anchoring adhesive - gives installers the flexibility to use the plug across multiple adhesive products without needing separate delivery components.
• Suitable for a wide range of installation orientations and conditions - engineered for overhead, upwardly inclined, and horizontal applications, as well as deep embedments and submerged underwater concrete conditions, reducing the need for orientation-specific tools.
• Compatible with glued-in-rod installations in timber when paired with Timber-SET structural epoxy anchoring adhesive - consistent adhesive distribution supports bond quality along the embedment depth for high-strength glued-in-rod connections, expanding the plug's utility beyond concrete applications.
• Model number embossed on each plug - allows for fast, accurate identification on the job site, helping crews avoid mix-ups when multiple plug sizes are in use.

Why This Product

• Engineered to reduce installation failures caused by voids - the matched tolerance fit virtually eliminates air pockets during adhesive dispensing, which directly supports the structural integrity of threaded rod and rebar dowel installations in concrete.
• Versatile enough for the most demanding site conditions - whether the application involves overhead anchoring, deep embedments, or fully submerged underwater concrete, this piston plug is designed to perform consistently across all of those scenarios with the same delivery system.
• Expands to timber structural applications - unlike basic concrete anchoring accessories, this plug size can also support high-strength glued-in-rod connections in timber when used with Timber-SET structural epoxy anchoring adhesive, making it a multi-substrate tool for structural contractors.
• Simplified on-site workflow - the embossed model number and compatibility with any Simpson Strong-Tie anchoring adhesive mean less time spent verifying components and more time completing installations accurately.

Frequently Asked Questions

What is the Simpson PP100-RP10 piston plug used for?

The PP100-RP10 adhesive piston plug is used with the Simpson Strong-Tie Piston Plug Delivery System to dispense adhesive into drilled holes for threaded rod and rebar dowel installations. It is designed for overhead, upwardly inclined, and horizontal orientations, as well as deep embedments and submerged (underwater) concrete conditions.

How does the piston plug prevent voids and air pockets?

The matched tolerance design between the piston plug and the drilled hole virtually eliminates the formation of voids and air pockets during adhesive dispensing, ensuring consistent adhesive placement and supporting bond quality along the full embedment depth.

Can this piston plug be used with timber installations?

Yes. The PP100 piston plug size can also be used for glued-in-rod (GIR) installations in timber when paired with Timber - SET structural epoxy anchoring adhesive. The consistent adhesive distribution it provides supports bond quality along the embedment depth for high - strength GIR connections.

Is the PP100-RP10 compatible with all Simpson Strong-Tie anchoring adhesives?

Yes. The PP100-RP10 piston plug is compatible with any Simpson Strong-Tie anchoring adhesive, making it a versatile component within the Simpson Strong-Tie Piston Plug Delivery System.
