EFIELD Pex-A Tubing 1-Inch 100 Ft Blue + 100 Ft Red
EFIELD offers Pex-A pipe with a total 200 ft of tubing in blue and red, plus a pipe cutter. This set emphasizes the flexibility of Pex-A for potable water and plumbing, with expansion capability for connections. The product is positioned as directly from a major Pex system manufacturer, supporting hot and cold water installations with a focus on ease of use and long-term reliability.
PEX Tube 1/2 Inch 100ft 2 Rolls EVOH Barrier
Likeem’s 1/2″ PEX tubing comes in two 100-foot rolls with red and blue color coding, featuring EVOH barrier for non-oxygen leakage resistance. The tubing is designed for easy installation with compatibility across crimp, push-to-connect, and clamp fittings. It emphasizes durability, resistance to cold and hot temperatures, and a wide operating range.
SharkBite 1 Inch x 100 Feet Blue PEX-B Pipe
This SharkBite blue PEX-B tubing supports long runs with coils up to 1,000 feet, reducing leak points and installation time. It is designed to resist chlorine and maintain performance under freeze-thaw conditions. The push-to-connect design offers faster setup compared with rigid piping, making it a practical option for residential potable water and heating systems.
GUOFIS All-in-One PEX Kit: 200 Ft 1/2″ Red/Blue Tubing
The GUOFIS kit bundles 200 feet of PEX tubing (100 ft red, 100 ft blue) with a 2-in-1 ratchet crimping tool, 30 stainless steel clamps, and a pipe cutter. It aims for easy DIY installation, enabling quick color-coding of hot and cold lines. The included cinch tool consolidates crimping and removal tasks for secure connections.
SUPPLYGIANT Pex-A 1-1/2″ 100 ft Coil
SUPPLYGIANT’s PEX-A tubing emphasizes flexibility and ANSI/ASTM compliance, featuring a red/white or blue color approach for easy color coding. The coil length supports radiant floor heating or hydronic applications with a focus on bend radius and compatibility across joining methods, including clamps and sleeves.
Buying Guide
Key considerations when selecting 1/2″ PEX tubing:
- PEX Type: PEX-A offers the highest flexibility and expansion capabilities, PEX-B provides strong resistance to scaling and chlorine, and PEX-C is typically used where cost savings matter. Evaluate based on project needs and local codes.
- Barrier Type: EVOH or non-oxygen barrier affects oxygen diffusion and system longevity. Radiant heating often benefits from barrier tubes to reduce corrosion risk.
- Color Coding: Red and blue tubes help distinguish hot and cold lines quickly during installation and future maintenance.
- Fittings and Tools: Crimp, expansion, or push-to-connect fittings require appropriate tools. All-in-one kits can simplify DIY projects but verify compatibility with existing fittings.
- Temperature and Pressure Ratings: Check the tubing’s rated maximum temperatures and pressures for your climate and system (e.g., radiant floor heating, domestic hot water).
- bend Radius: Tubing with smaller bend radii makes tight routing easier but ensure the radius meets the tubing’s minimum to prevent kinking.
- Certification and Standards: Look for ANSI, ASTM, CSA, or CAN/ULC marks to ensure compliance with building codes and safety standards.
- Warranty and Manufacturer Support: Longer warranties and responsive support can be valuable for complex installations or DIY learners.
In summary, the choice between products should align with your project scope, whether it’s a simple home repair, a full radiant heating system, or a new install. Balance tubing flexibility, barrier requirements, and tool compatibility to minimize leaks and maintenance over time.
