What Is Pro-Flex Yellow CSST?
Pro-Flex Yellow CSST is corrugated stainless steel tubing designed for fuel-gas piping systems. Its flexible construction allows the tubing to be routed through building structures with fewer directional fittings than many traditional rigid steel installations.
Pro-Flex describes its CSST system as a labor-saving alternative to black steel pipe. Because the tubing is flexible, installers can route it around many obstacles without cutting and threading multiple sections of rigid pipe.
The yellow-jacket tubing is part of the traditional Pro-Flex CSST product family and uses compatible Pro-Flex fittings and installation components.
Why Choose Flexible CSST?
Flexible Installation
- Tubing can be routed around many building obstacles
- Reduces reliance on numerous directional fittings
- Can simplify long or complex gas piping runs
- Useful in residential and light-commercial construction
- Available in long continuous lengths
Labor-Saving Design
- Reduces cutting and threading compared with rigid steel pipe
- Fewer fittings may be required for many layouts
- Flexible tubing can reduce installation steps
- Annealed tubing is designed to bend and remain in position
- Available in multiple coil and spool lengths
Available Lengths
PFCT-011425 – 25' Coil
The PFCT-011425 provides 25 feet of 1-1/4" ID Yellow Jacket CSST. The shorter coil is useful where the project requires a limited tubing run or where a compact coil is easier to transport and handle.
PFCT-011475 – 75' Coil
The PFCT-011475 provides 75 feet of 1-1/4" ID Yellow Jacket CSST, offering additional continuous tubing length for larger gas piping installations.
PFCT-0114 – 150' Spool
The PFCT-0114 provides 150 feet of 1-1/4" ID Yellow Jacket CSST on a spool for projects requiring longer continuous gas piping runs.
Common Applications
Residential Gas Piping
- Gas distribution mains and branches
- Furnaces and boilers
- Water heaters
- Gas ranges and cooking equipment
- Fireplaces and other gas-fired appliances
Mechanical & Light-Commercial Systems
- Mechanical-room gas distribution
- Multiple-appliance gas systems
- Long gas piping runs
- Retrofit gas piping installations
- Applications where flexible routing reduces rigid-pipe fittings
Pro-Flex Yellow CSST Features
The Pro-Flex product guide describes Yellow CSST as a cost-saving alternative when electrical bonding is required and emphasizes its labor savings compared with black steel piping. The manufacturer also identifies the tubing as annealed, with a "no spring back" characteristic that allows the tube to bend and remain bent.
The 1-1/4" Yellow CSST product family is offered in several lengths so installers can select a coil or spool appropriate for the expected piping run.
Standards & Listings
The Pro-Flex product guide identifies the CSST system with the ANSI LC1 / CSA 6.26 standard for fuel-gas piping systems using corrugated stainless steel tubing. It also lists CSA Group Certificate of Compliance #1174673 and IAPMO File #3669 for the Pro-Flex CSST system.
Always verify current manufacturer documentation, approvals, and local code requirements for the specific installation.
Choosing the Correct Length
| Part Number | Length | Package Type | Typical Selection Consideration |
|---|---|---|---|
| PFCT-011425 | 25' | Coil | Shorter gas piping runs |
| PFCT-011475 | 75' | Coil | Medium-length continuous runs |
| PFCT-0114 | 150' | Spool | Longer continuous installations |
Installation Considerations
- Confirm that 1-1/4" CSST provides sufficient gas capacity for the planned system.
- Size the tubing according to gas type, supply pressure, developed length, and connected appliance load.
- Use compatible Pro-Flex fittings and installation components.
- Follow current Pro-Flex CSST installation instructions.
- Provide electrical bonding where required for the Yellow CSST system.
- Protect the tubing against physical damage where required.
- Use striker plates and protective devices where specified by the manufacturer and applicable codes.
- Properly support the tubing according to installation requirements.
- Pressure-test and leak-test the completed gas piping system as required.
- Installation should be completed by qualified gas-piping personnel.
