SharkBite 1/4 in x 3/8 in Compression Stop Valve Connector - Easy Push

In this review the SharkBite 1/4 in (3/8 in OD) x 3/8 in compression stop valve connector is evaluated for homeowners and tradespeople who need a fast, reliable way to connect PEX to fixtures. The bottom line: this pack of six brass, push-to-connect fittings excels when speed and ease of installation matter most, because it eliminates crimping, soldering, or glue and works in tight under-sink spaces as well as on wet lines. It is a practical choice for repair work, appliance hookups, and small remodels where a neat chrome finish and durable construction are useful.

Key Features

• Push-to-connect design: Installs quickly without tools, letting a competent DIYer or plumber complete a connection in seconds.
• Compression adapter compatibility: Connects 1/4 in (3/8 in OD) PEX pipe to standard 3/8 in compression fixture fittings used on faucets and refrigerators.
• Works in wet lines: Can be installed on live water lines, reducing downtime while performing repairs or replacements.
• Durable brass construction: Brass body and reliable internal components give commercial-grade durability suitable for repeated service.
• Sleek finish: Chrome appearance provides an attractive exposed look for visible installations under sinks or behind appliances.
• Made in the USA: Manufactured and tested domestically to the brand's commercial and residential standards.

Who It's For

This fitting is best for homeowners doing quick repairs, plumbers needing a fast on-the-job solution, and installers hooking up faucets, refrigerators, or humidifiers where a 3/8 in compression connection is required. It particularly suits projects in tight spaces where using a torch or crimp tools is impractical.

Those working on specialty or nonstandard piping systems, or who prefer permanent soldered joints for invisible, long-term installs, may look elsewhere. Also, if a project requires a different size or material not listed here, choose a fitting matched to that specification.
