Vruelia CSST Flexible Propane Gas Line 3/4" x 37 ft — Yellow PE Jacket, 150K BTU

Vruelia CSST Flexible Propane Gas Line 3/4" 37 ft is a code-rated, corrugated stainless steel flexible gas hose wrapped in a durable yellow PE jacket engineered to deliver propane or natural gas reliably for whole-home and outdoor systems.

This flexible gas line combines a thick 304 stainless-steel corrugated core with a protective polyethylene outer jacket, making it suitable for buried runs, outdoor appliances, and indoor routing where rigid pipe would be impractical. The 3/4" ID (0.875") capacity supports higher BTU demands up to 150,000 BTU, and the supplied brass NPT male connectors simplify hookups right out of the box. It’s offered in a 37-foot length to cover long runs without multiple joints, and the product is manufactured and pressure-tested to industry standards for plumbers, contractors, and experienced DIYers.

How does this 3/4" CSST line perform for high-BTU appliances?

The 0.875" inside diameter allows ample flow for whole-home systems and high-demand outdoor equipment. It is rated to handle up to approximately 150K BTU, so it’s appropriate for applications such as large grills, pool heaters, and main house feeds when sized correctly.

• 0.875" ID designed for high-volume gas delivery and minimal pressure drop
• Capacity suitable for many whole-home and outdoor appliance setups (up to ~150,000 BTU)
• Dual-fuel compatibility with natural gas and propane for flexible installations

What makes the Vruelia CSST durable and code-friendly?

Vruelia uses a 0.012" thick 304 stainless-steel corrugated tubing core—substantially thicker than many imports—then pressure-tests each line to 15 PSI and certifies it to ASTM B280 standards. The yellow polyethylene jacket resists abrasion, UV, and corrosion and allows safe outdoor burial to specified depths.

• 304 stainless-steel core at 0.012" thickness for longevity and strength
• Yellow PE jacket rated for -40°F to 400°F temperature extremes
• ASTM B280 certified and 15 PSI pressure-tested for professional compliance

How easy is this gas line to install and customize?

The line ships with two solid brass NPT male quick-connect adapters pre-attached, and the corrugated tubing can be cut to length with a tubing cutter for custom runs. Many installers report significantly faster labor compared to black iron, and the flexible tubing navigates attics, joists, and walls with minimal demolition.

• 37 ft length reduces need for multiple joints and fittings
• Comes with two brass NPT connectors; extra fittings can be added after cutting
• Recommended tools: tubing cutter, adjustable wrenches, tape, and thread sealant tape

Is this product safe for underground and seismic-zone installations?

The corrugated stainless core flexes under movement, offering greater earthquake resilience than rigid pipe. When buried, the rugged yellow jacket protects against soil abrasion and weathering; always follow local code for burial depth and handling.

• Corrugated design absorbs movement to reduce stress fractures during seismic events
• Yellow jacket permits outdoor burial and protects against corrosion and abrasion
• Follow local building code for bonding, burial depth, and licensed installation requirements

Who is this for? The Vruelia 3/4" CSST 37 ft line is aimed at licensed plumbers, HVAC contractors, builders, and confident DIY homeowners who need a single long run capable of supplying high-BTU appliances or a whole-home branch. It’s a strong choice when you want to replace heavy rigid pipe with a flexible, faster-to-install solution that meets industry standards—provided installation and pressure testing are performed by qualified personnel or under professional supervision.
