2-Way Inline Straight Sleeve Pipe Connector (frequently called an In-Line Tubing Joiner, Sleeve Coupler, or Extension Splice).Unlike internal flush mandrel connectors that slide entirely hidden inside the tube, this sleeve acts as an external collar. It slides over the outside of two separate pieces of tubing to securely lock them together end-to-end, making it highly useful for lengthening handrails, bimini tops, or structural frames.
Key Features & Specifications
Four-Point Locking Stability: Features four heavy-duty hex socket set screws (arranged symmetrically in pairs on opposite ends). This provides powerful, multi-directional clamping force that keeps both connected tubing sections from twisting, bowing, or pulling apart under high loads.
AISI 316 Heavy Casting: Formed from heavy-walled, precision-cast 316 Stainless Steel and finished with an ultra-smooth mirror polish. It prevents rust streaks and galvanic corrosion between joined tubing components on boat decks or architectural fixtures.
Clean Butted Joint: Designed so that the two stainless steel tubes slide inside and meet exactly at the hidden center of the sleeve, providing a sturdy, continuous straight rail extension with minimal protrusion.
To ensure this sleeve slides smoothly onto your existing setup, let us know:
What is the exact Outer Diameter (O.D.) of the tubes you are trying to splice together (e.g., 7/8" / 22mm, 1" / 25mm, or 1-1/4" / 32mm)?
Will this joint be exposed to significant overhead body weight (like a safety boarding grab handle) or used for a framed canopy structure (like a Bimini top frame)?
