Simpson PP112-RP10 Adhesive Piston Plug for 1-1/8 in. Hole Diameter is a precision-engineered plastic plug from Simpson Strong-Tie designed for use with the Simpson Strong-Tie Piston Plug Delivery System. This system is purpose-built for dispensing adhesive into drilled holes for threaded rod and rebar dowel installations in overhead, upwardly inclined, and horizontal orientations, as well as deep embedments 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, supporting consistent, high-quality bond results.

Frequently Asked Questions

What is the purpose of the Simpson PP112-RP10 Adhesive Piston Plug?

The adhesive piston plug works in conjunction with the Simpson Strong-Tie Piston Plug Delivery System to dispense adhesive into drilled holes for threaded rod and rebar dowel installations. Its matched tolerance design virtually eliminates the formation of voids and air pockets during adhesive dispensing, ensuring consistent adhesive placement along the full embedment depth.

What drilled hole diameter is this piston plug sized for?

The PP112-RP10 is sized to fit a 1-1/8 in. drilled hole diameter, and is compatible with the matched-tolerance Piston Plug Delivery System components designed for that hole size.

Can this piston plug be used with any Simpson Strong-Tie adhesive?

Yes. The PP112-RP10 works with any Simpson Strong-Tie anchoring adhesive. Additionally, this piston plug size can be used for glued-in-rod (GIR) installations in timber when paired with Timber - SET structural epoxy anchoring adhesive.

Is the PP112-RP10 suitable for challenging installation orientations such as overhead or underwater applications?

Yes. The Piston Plug Delivery System is specifically designed for dispensing adhesive in overhead, upwardly inclined, and horizontal orientations, as well as deep embedments and submerged (underwater) concrete conditions. The matched tolerance between the plug and hole helps maintain adhesive placement integrity across all of these challenging scenarios.
