Installation tips
Prepare the threads by cleaning them thoroughly. Use a compatible thread sealant or PTFE tape designed for stainless steel and the fluids in your system. Tighten by hand first, then snug with a appropriate wrench—avoid excessive torque to prevent thread damage and leaks. If you’re reworking an assembly later, choose a sealant that supports disassembly and long-term integrity in stainless fittings.
Maintenance and care
To maximize longevity, keep the fitting clean and dry when not in service and inspect for signs of wear or corrosion in humid or moist environments. The stainless steel construction is designed to withstand repeated assembly and disassembly in low-to-medium pressure applications, helping your piping system stay reliable over time.
