Hollaender 70-9 External Coupling
The Hollaender 70-9 is an aluminum external coupling designed to join two sections of 2-inch nominal pipe. It provides a straight, corrosion-resistant connection for structural frameworks used in grounds maintenance and outdoor storage builds. The gray mill finish suits exposed environments where durability matters.
Fits 2 3/8 inch outer diameter pipe
The coupling accepts pipe with an actual outside diameter of 2 3/8 inches and an inside diameter of 2 3/8 inches, slipping over each end to create a continuous run. Its overall length of 4 1/8 inches adds minimal protrusion, keeping the assembled frame compact. No threading or welding is required, so installation only needs basic hand tools and the matching pipe stock.
Meets ASTM B179 535 for sustained outdoor use
The aluminum alloy conforms to ASTM B179 535, giving consistent corrosion resistance through seasonal temperature swings and moisture cycles. The material does not rely on a coating that can wear away, so the joint retains its integrity over long service periods. It is not intended for pressurised fluid systems or load-bearing splices that exceed the fitting’s structural rating.

Questions about this item
What pipe size does the 70-9 external coupling accept?
The 70-9 external coupling fits a 2 in pipe with an actual outer diameter of 2 3/8 in and an inside diameter of 2 3/8 in.
How does the aluminum fitting handle heat and corrosion during all-day exposure?
The aluminum construction is corrosion resistant and carries a mill finish that withstands continuous outdoor exposure without rust.
What structural pipe standard must the mating pipe meet for this coupling?
The coupling is made to ASTM B179 535, so the connecting pipe should conform to that specification for a proper fit.
