SIGMA offers the widest selection of fittings on the market today. Our quality assurance protocols exceed industry standards; we require that every single fitting be hydrotested before it leaves the factory. Our fittings all have alpha-numeric heat codes which provide 100% traceability. This is SIGMA’s way of making sure that ours are the safest and most reliable fittings that money can buy.
