About TSI Products
TSI Products is an Arlington, Texas-based, privately held manufacturer best known for its Supercool line of automotive air conditioning service supplies. The company traces its roots to 1985, when it started as Texas Saddlebags, Inc. and built one of the first automotive consoles with built-in storage and cup holders. Over the years it moved into plastic injection molding and grew into a U.S. manufacturer that designs, prototypes, tests and builds products in-house. Today, technicians and DIYers know TSI Products for the consumables and small parts that keep A/C systems sealed, lubricated and leak-free.
Why A/C Consumables Matter
An automotive A/C system is a closed loop, and its reliability often comes down to small details: the right oil viscosity, a fresh seal at every fitting, and a clean system before new components go in. TSI Products focuses on exactly these details, with parts such as green HNBR O-rings, stainless steel Ford garter springs, tear drop sealing washers and high side valve cores. HNBR is the preferred material for modern refrigerants and oils, which is why assortments built around it are a staple in professional shops.
Refrigerant Oil for Modern and Legacy Systems
Compressor lubrication is where TSI Products is especially well known. Its refrigerant oil range includes PAG formulations such as PAG 150, ester oils for R134a and R12 systems, and POE-based oils formulated for R1234yf systems that are also suited to hybrid and electric compressors. Choosing the correct oil type and viscosity is critical, since mixing incompatible lubricants can shorten compressor life.
Cleaning Out and Repairing the System
When a compressor fails or a system has been contaminated, debris and old oil need to be removed before reassembly. TSI Products offers an A/C system flush selection to help clear lines, condensers and evaporators so new parts are not damaged by leftover contaminants. For hands-on service work, the brand's A/C repair tool offering supports tasks like fitting installation and seal replacement. Its leak stop with UV dye products are also designed to help seal minor leaks in rubber components while making the source easier to trace.
What to Consider When Shopping
- Refrigerant type: Confirm whether the vehicle uses R134a, R1234yf or an older R12 retrofit before choosing oil.
- Oil compatibility: Match PAG, ester or POE oils to the system and compressor type, especially for hybrid and electric vehicles.
- Seal material: HNBR O-rings offer better durability than standard nitrile in A/C service.
- Service sequence: Flush, replace seals, and then recharge with the correct oil for the best long-term results.
With a catalog built around practical A/C service needs, TSI Products gives technicians a dependable source of the small parts and fluids that make a repair last.
