Engineering Overview
Brass press fittings represent a technological advancement in mechanical piping connections, utilizing cold-working technology to create permanent joints without heat or chemical adhesives. These fittings incorporate precision-engineered brass bodies with integrated stainless steel compression sleeves that deform under controlled pressure to form leak-proof seals. The dezincification-resistant (DZR) brass construction provides superior corrosion resistance while maintaining the material’s inherent antimicrobial properties essential for potable water systems.
