FAQ

Q: Can the Coupling ISO 4144 be used to connect pipes of different thread standards?

A: The coupling's internal threads are compatible with ASME, DIN and ISO male pipe ends of the same size, so it can connect pipes of different thread standards (e.g., ASME to DIN) without additional adapter parts for standard 150lbs applications.

Q: What maintenance is required for this coupling in long-term industrial use?

A: The 304/316 stainless steel construction is corrosion-resistant, so no regular maintenance is required for standard indoor/outdoor industrial applications; visual inspections for thread damage are recommended every 12 months for underground or corrosive environments.

Q: Do you provide gaskets?

A: We offer compatible food-grade and industrial-grade gaskets for all sizes of the Coupling ISO 4144 as a complementary product, with gasket material options matching the coupling's media compatibility requirements.
