Practical installation tips:

• Align the buttress and socket ends carefully before tightening to avoid cross-threading.
• Ensure the o-ring seats evenly against the mating surface for a proper seal.
• Tighten by hand first, then use an appropriate tool to snug the connection—do not overtighten, to protect the o-ring and threads.
• After installation, run a gentle water test to verify there are no leaks around the union.
