FAQ

What does ‘not pull-out-resistant’ mean for this Straub coupling?

This means the coupling seals the pipe connection but does not provide axial restraint. The pipes must be independently anchored to prevent them from pulling apart under pressure or thermal expansion.

What types of fluids is the EPDM gasket suitable for?

The EPDM (Ethylene Propylene Diene Monomer) gasket is excellent for water, wastewater, air, and many chemical applications. It is not suitable for hydrocarbon-based fluids like oils or fuels.

Can the OPEN-FLEX 1 be used for pipe repair?

Yes, the hinged ‘OPEN-FLEX’ design is specifically intended for easy installation on existing pipelines, making it ideal for repairs or modifications without needing to cut or dismantle the pipe system.
