When selecting gasket materials for pipe couplings, NBR, EPDM, and Viton are the three critical elastomer options that dominate Singapore’s industrial, maritime, and HVAC sectors. The gasket is the seal — in a mechanical pipe coupling, whether it’s a grooved coupling, repair clamp, or flexible connector, the housing holds the joint together, but the gasket … Read more

This pipe coupling size chart covers DN15 to DN300 — giving you OD ranges, bolt specs, pressure ratings, and gasket selection for mechanical pipe couplings in one complete reference. Choosing the right coupling starts with one number: the actual outside diameter (OD) of your pipe. Not the nominal bore. Not the DN size. The OD. … Read more
