Introducing the Plumb Pak 3/8 in FIP x 3/8 in Compression Brass Straight Connector — a compact, dependable link built for reliable potable-water connections in tight spaces. With a 3/8" female pipe thread on one end and a 3/8" compression end on the other, this straight connector streamlines assembly where space is at a premium, delivering a clean, secure transition between thread-and-terrified components and tubing.
Why this connector stands out
-
Lead-free brass construction — safe for potable water and built to resist corrosion over the long term.
-
Dual-end versatility — one end accepts 3/8" FIP threads, the other clamps onto 3/8" tubing via a compression fitting, enabling straightforward, solder-free installation.
-
Compact, straight design — ideal for confined spaces and installations where angled fittings aren’t feasible.
-
Retail-ready packaging — carded packaging makes it easy to stock, display, and grab for quick repairs in the field.
-
Durable, purpose-built connector — designed to provide a dependable seal and steady flow in everyday plumbing tasks.
-
Not ANSI certified — explicitly noted for transparency about certification status.
Ideal use cases
- Connecting a 3/8" compression tube to a fixture or valve with a 3/8" FIP thread.
- Quick-field repairs where space prevents bending or soldering, such as under sinks, supply lines, or small-appliance connections.
- Homemade or retrofit projects that require a reliable brass bridge between threaded and compression connections.
Practical installation tips
- For the FIP end, use an appropriate thread sealant or PTFE tape on male threads to ensure a watertight seal. Tighten to manufacturer guidelines with a wrench, and avoid overtightening to prevent thread damage.
- On the compression end, pair the connector with a matching 3/8" tubing, and use a compatible compression nut and ferrule. Tighten evenly to achieve a snug, leak-free fit.
- Inspect connections after initial pressure test and periodically thereafter, especially in high-usage areas or with temperature fluctuations.
