30pcs 3/4ft PEX Fittings Set - Tees Elbows Couplings Combo

In this review the reviewer tested the 30pcs 3/4' PEX fittings set and found it best suited for DIY plumbers and homeowners tackling hot and cold water runs. The bottom line: this brass combo offers a full selection of tees, elbows and straight couplings that install quickly with crimp rings and give reliable, leak-free joins for standard PEX tubing. If you need a bulk set to replace a supply line or stock a toolbox, this kit stands out for its practical mix and straightforward compatibility with common PEX-A, PEX-B and PEX-C tubing.

Key Features

• Complete kit: Includes 10 tees, 10 elbows and 10 couplings so a single purchase covers multiple connection types for a single project or repairs.
• Durable brass construction: Brass body resists corrosion and high temperatures, offering longevity for hot water and cold water systems up to the rated range.
• Wide compatibility: Works with PEX-A, PEX-B and PEX-C tubing manufactured to North American SDR-9 standards for broad use with commonly available PEX brands.
• No solder or flame: Crimp-style installation removes the need for soldering, flux or bonding agents, simplifying repair and replacement jobs.
• Standards compliant: Manufactured to ASTM F2159, ASTM F877 and NSF standards for potable water use and reliability in residential plumbing.

Who It's For

This set is aimed at homeowners, handymen and small contractors who need a reliable stock of 3/4' fittings for water supply work. It is particularly useful for replacing supply lines, running new bathroom or kitchen branches, or keeping spare fittings in a service van.

Those who should look elsewhere include installers using PEX-AL-PEX or expander-style systems, and anyone working with PB tubing, since these fittings are not compatible with expander fitting systems or multilayer PEX-AL-PEX tubing.

Pros & Cons

Pros

• Good value: a full set of tees, elbows and couplings at a single price covers many common plumbing needs.
• Easy installation: crimp fittings mean no flame, solder or solvents, which speeds work and reduces tool needs.
• Solid sealability and fit: customers report no leaks and a snug fit on standard PEX tubing.
• Durable material: brass construction resists rust and high temperatures encountered in standard residential systems.

Cons

• Not universal: incompatible with PEX-AL-PEX, expander systems and PB tubing, so verify your pipe type before buying.
