Product details
The Fernco Hulk is a universal coupling per nominal size that connects most pipe materials. Installation is as easy as sliding the coupling on and torquing the stainless-steel bands down for a leak-proof connection. Fernco couplings have been proudly manufactured in the USA since 1964 and are made of the highest quality elastomeric polyvinyl chloride and corrosion-resistant, rust-proof clamps. With a reputation for quality, innovation, and reliable performance, you can trust Fernco as the global leader in flexible plumbing couplings.
One coupling, endless possibilities. Designed to connect a wide range of pipe materials within the same nominal size, the Hulk Coupling is your go-to solution when pipe types vary unexpectedly. Whether it's clay to SDR-35, or concrete to ductile iron, The Hulk Coupling adapts-so you're never caught off guard.
Built for underground performance. Engineered as a heavy-duty, non-shear coupling, the Hulk is reinforced with embedded stainless steel rods to resist shear forces caused by ground movement or pipe misalignment.
Standards you can trust. The Hulk coupling meets and exceeds ASTM C 1173 and CSA B602, proving it's more than just muscle-it's certified strength.
