Paircoil

PAIRCOIL

Paircoil is one of our flagship products. It’s a pre-insulated copper tube line set engineered for speed and durability. As it comes pre-paired and pre-insulated, installing suction lines for ductless systems is faster and more accurate.

Not just high-quality, Paircoil meets ASTM standards for flame and smoke ratings and is compatible with R32 refrigerants, found in most modern HVAC systems. It also offers wear resistance, UV protection, and hand-bendable flexibility to prevent kinks during installation.

Paircoil copper tube linesets are designed for efficiency, coming pre-paired and pre-insulated to significantly speed up installation time. Built to meet the highest industry standards, it boasts nine ASTM ratings, including the ASTM E84 (25/50) Made from high-quality annealed copper, Paircoil is easy to flare and flexible enough to bend effortlessly. The insulation is both robust and pliable, offering superior protection against wear and tear over the long term. A2L compatible and available in a range of sizes, Paircoil is the go-to choice for contractors who demand reliability and efficiency.

TIME SAVING

The linsets come pre-paired insulated liquid and suctions lines allow for labor-saving single-run installation of both lines

ASTM Rated

Engineered to exceed industry standards, it holds nine ASTM ratings—including the ASTM E84 (25/50) for fire and smoke.

WEAR RESISTANCE

The anti-friction coating helps prevent damage during installation and ensures strong tape adhesion. Tough yet flexible, the material can be quickly cut and separated by hand

Hand Bendable

Malleable copper with dense foam insulation can be quickly and easily bent by hand or tools, helping to prevent kinks during installation.

Q. Is the insulation for Paircoil UV resistant?

A. Paircoil has met the standard for ASTM G154 for UV exposure. It is also recommended to use our SLIMDUCT products to provide extra protection against damages that may be incurred due to accidental damage, pests or other external forces.

Q. Are cable ties included in the Paircoil packaging?

A. Cables ties are not included and must be purchased separately.

Q. Are both ends of Paircoil flared?

A. Paircoil is not flared and flare nuts are not included. The installer will flare based on the application and will use the flare nuts provided by the equipment manufacturer.

Q. Is Paircoil compatible with R32 refrigerants?

A. Yes, Paircoil has been tested to 700 psi which is more than enough for HVAC applications with current refrigerants.

Q. Can these products be used for applications outside of heating and air conditioning?

A. Paircoil is designed and manufactured specifically for use in air conditioning systems. Our warranty does not cover any use outside of Air-conditioning or Heat pump applications.

Q. I want to hide the lineset. Are there any precautions I should know about?

A. There are many ways to hide linesets such as within a wall or attic space. Both of those options come with code restrictions based on fire and safety. You may also bury the linesets but there are specific methods to ensure the longevity of the copper tubing. Please reach out to the governing code authority for specifics for either option.
Installing the lineset down an exterior wall and covering it with our SLIMDUCT product is the preferred method. This provides additional protections from UV rays, pests and other external factors that may cause damage.
SLIMDUCT offers a variety of fittings and colors to fit most any exterior design.

Q. How can I protect the insulation in an application where the lineset is exposed?

A. Paircoil linesets have a UV rating and can last for years with no issues. For extra protection, you may use our UV Resistant Tape (UVT), which has been proven to be excellent at withstanding UV rays.
