SharkBite 3/4 in x 300 ft Blue PEX-A Tubing - Flexible Plumbing Coil

In this review the SharkBite 3/4 in x 300 ft Blue PEX-A tubing is evaluated for plumbers, contractors and DIYers who need long runs of potable water line with fewer fittings. The bottom line: its high flexibility and compatibility with multiple connection systems make it a practical choice when reducing installation time and potential leak points is a priority. The coil is made in the USA and is specifically intended for hot and cold potable water systems, so those seeking a rugged, installation-friendly PEX option will find this product worth considering.

Key Features

• Flexible PEX-A construction: Allows longer continuous runs and fewer fittings, cutting labor and material costs on typical residential plumbing jobs.
• Easy installation: Bends around corners without elbows and works with cold expansion for fluted-end fittings to simplify connections and preserve flow.
• Certified compatibility: Works with PEX expansion (F1960), push-to-connect (ASSE 1061), plastic crimp (ASTM F2159) and brass crimp (ASTM F1807) for wide fitting options.
• Durable and UV-tolerant: PEX-A construction resists kinks better than rigid pipe and tolerates up to six months of UV exposure for staging on site.
• Rated performance: Handles a broad temperature range and pressures suitable for domestic hot and cold potable water systems.

Who It's For

The tubing is best for residential plumbers, remodel contractors and experienced DIYers who need a long, continuous line for hot and cold potable water and want fewer fittings to reduce potential leak points. It is also a good match for mobile applications like RV plumbing where flexibility and compact coil storage matter.

Those who should look elsewhere include installers requiring rigid pipe for structural runs, or projects that demand permanent above-ground UV exposure longer than six months without protection. If you need specialty chemical resistance or ratings beyond domestic potable water systems, choose a product specified for that use.

Pros & Cons

Pros

• High flexibility reduces the number of fittings and shortens install time compared with rigid pipe.
• Works with multiple connection methods, so it integrates with common PEX systems and fittings.
• Durable PEX-A resists kinks and is manufactured in the USA, giving confidence in material quality.

Cons

• Flexibility feedback is mixed: some users find it less flexible than expected for very tight bends, requiring careful handling.
