This coupling with stop is a press-to-connect fitting designed to join sections of copper pipe quickly and securely in plumbing and mechanical systems. Its integrated stop simplifies installation by limiting insertion depth, helping ensure consistent connections without soldering, threading, or open flame. Equipped with smart connect technology and EPDM sealing elements, it supports efficient, leak-resistant performance and helps installers verify proper press engagement, making it ideal for potable water and compatible applications.
