Take the strain, pain, and worry out of making those delicate copper piping bends with Pioneer's newest flexible line set for ductless mini split systems. Prevent kinks, avoid bending complications, and gain freedom when it comes to routing runs.

Traditional line sets are typically made of soft copper which is not always ideal for certain installations, as it is prone to kinking or toughening with tight or repeated bends. This product solves that dilemma by offering a tougher steel construction, allowing for deployment in more unique environments requiring greater flexibility or a tighter bend radius.

This product is approved for usage on air conditioners and heat pumps as liquid, suction, hot gas discharge line use, as long as none of these uses exceeds the maximum recommended operating pressures indicated on the equipment.


  • Set of 2 Stainless Steel Pipes w/ Black Rubber Insulation
  • Compatible with Flare-type mini split connections
  • Improved bending radius over copper linesets
  • Suitable for most project and applications


  • Design Pressure: 650 PSIG
  • Max abnormal pressure 3600 PSIG
  • Length: 16 feet
  • Insulation thickness: 1/2"
  • Diameters selected when adding to cart
  • Working temperature: -40°F ~ 248°F

This is a specialty product and cannot be shortened, patched, or repaired.

Shipping Details

We only ship to the 48 contiguous United States. No shipments to APO/FPO addresses, AK, HI, PR or other US Territories. No international shipments. Due to the size and the weight of our equipment, we can only utilize well known freight companies for shipping. Each shipment will be palletized, strapped down and wrapped in stretch film to protect against damages during transit.

Upon arrival you may ask the driver to break down the palette into individual cartons to unload the goods from the truck easily. We generally include Lift Gate service. This will arrive as curb side delivery. Trucker will unload the goods from the truck to ground level. If you must have inside delivery service, there will be an additional charge which needs to be paid separately and coordinated with the freight company. We also allow free pickup from our main distribution warehouse, located in Miami area. Equipment we sell is not suitable for express or courier shipping because of their weight as well as high risk of damages.

Due to higher than expected order volume and busy sales season, larger orders may take an extra 3-5 days to be prepared for shipment. We are working around-the-clock to ship out all orders in a timely manner, and will communicate with you if there are any unexpected delays or questions.

We prepare each shipment within 72 hours after the receipt of payment (only during weekdays). Trucking companies usually pick up same day or a day after we call them that the shipment is ready. The transit may take any time between 5 to 8 business days and in rare cases up to 12 days.

We will provide tracking information after shipment. Please contact us in case of any shipment delays. CHECK YOUR INFORMATION CAREFULLY TO SUBMIT THE CORRECT DELIVERY ADDRESS, UPDATED EMAIL AND A VALID PHONE NUMBER with your order. Someone must be present to receive the cargo at the time of delivery. Delivery company will call your phone number to setup a delivery appointment for residential deliveries. If your phone number is not valid, the cargo can not be delivered and will be returned at your expense within 3 days of arrival. If the delivery is refused or can not be delivered, it will be handled as returned merchandise.

Upon arrival, count all cartons and compare with the number stated on the delivery receipt before signing. Open the cartons and inspect the goods carefully for any damages. All products have been inspected under strict ISO regulated facilities and leave our warehouse in perfect condition. Report any shipping damages to the freight carrier on the delivery receipt and file a claim. Also contact us with the description of damages and pictures, etc. Although rare, certain freight damages can occur and we are here to help.

We carry all necessary replacement and service parts and components in large quantities and make them available during and after the warranty period.
