Buying advice

Consider the application (hydraulics, pneumatics, or plumbing), pressure requirements, and material compatibility. Brass is common for water, stainless steel for high pressure/corrosive environments. Check pipe size and thread standards (NPT or BSP). For precision applications, invest in Swagelok; for budget projects, Mueller Streamline offers good value.
