The Simpson Adhesive Piston Plug for 11/16 in. Hole Diameter is a precision-fit plastic plug from Simpson engineered for use with the Simpson Strong-Tie Piston Plug Delivery System. Designed to dispense adhesive into drilled holes for threaded rod and rebar dowel installations, it performs reliably across demanding orientations including overhead, upwardly inclined, horizontal, deep embedment, and submerged (underwater) concrete conditions. The matched tolerance design between the piston plug and the drilled hole virtually eliminates the formation of voids and air pockets during adhesive dispensing, delivering consistent and dependable anchor performance in every application.

Key Features

• Model number embossed on each plug - makes it easy to identify the correct plug on the job site and avoid mix-ups when working with multiple hole sizes.
• Matched tolerance design between plug and drilled hole - virtually eliminates voids and air pockets during adhesive dispensing, resulting in more consistent and reliable anchor placement.
• Compatible with any Simpson Strong-Tie concrete anchoring adhesive - gives contractors flexibility to use the plug across a wide range of anchoring applications without needing separate accessories.
• Designed for varied installation orientations and embedment depths - supports overhead, upwardly inclined, horizontal, deep embedment, and submerged concrete conditions, reducing the need for job-specific alternatives.
• Barbed end for secure tubing connection - provides a reliable attachment to flexible extension tubing, helping maintain a sealed delivery path during adhesive dispensing.
• Sized specifically for 11/16 in. drilled holes - the precise fit is what enables the matched tolerance performance that controls void formation.

Why This Product

• Built for the toughest anchor installations - whether you are setting anchors in overhead concrete, submerged conditions, or deep embedment applications, this plug is engineered to handle orientations where standard dispensing methods fall short.
• Void-free adhesive placement where it matters most - the matched tolerance fit between the plug and the drilled hole virtually eliminates air pockets, which directly supports the structural integrity of threaded rod and rebar dowel anchors.
• Broad adhesive compatibility keeps your workflow simple - because the plug works with any Simpson Strong-Tie concrete anchoring adhesive, there is no need to stock separate dispensing accessories for different adhesive products.
• Easy identification saves time on multi-task job sites - the model number embossed directly on each plug means installers can quickly confirm they have the right plug for the hole size without consulting packaging.
