There are several types of transmission hoses available for your vehicle. Among them are Silicone hoses, Rubberized transmission cooler transmission lines, and NPT (National Pipe Taper) fittings. No matter what your budget or preference is, there will be one that suits your needs.
Silicone hoses
The transmission cooler line system is a vital part of the automatic transmission. It transports heated transmission fluid to the radiator, where it is cooled, and then returns the cooled fluid to the gearbox. The transmission may overheat if this line is damaged. One of the best solutions is to replace the damaged line with a new rubberized one. These are widely available and can be purchased from a local auto parts store. These hoses can be used to replace old metal lines and are easy to install.
The HPS ultra-high temperature reinforced silicone hose can replace the stock transmission fluid cooler coolant hose. This hose is engineered to prevent coolant leakage and prevent engine overheating. It also features heavy-duty stainless-steel spring-loaded tbolt clamps made of stainless steel that won’t cut through the hose. It has the correct curves and bends to prevent premature rupture of the hose.
Silicone hoses are suitable for a variety of automotive applications. While they are not recommended for fuel hoses, they can be used in many other areas of your car. They can be used to replace damaged or cracked hoses in your transmission cooler. They are also resistant to pressure, temperature, and chemicals.
A transmission cooler hose’s compatibility with different fluid types is another important feature. Transmission oil cooler hoses can be used in power steering systems in certain situations. It is important to remember that some power steering systems use mineral hydroil, which has different properties from conventional power steering fluid. To ensure compatibility, you can look for the SAE J-spec number on the old hose and match it with the corresponding number on the replacement hose.
Check the size of the lines to determine if silicone rubber hoses are right fit for your car. A 1/4-in line for a 7mm fitting will reduce flow by 19%. This will also stretch the outer covering of the hose and damage the internal reinforcement braid. This could lead to premature hose failure.
NPT (National Pipe Taper) fittings
NPT (National Pipe Taper) fitting is one of the most common types of pipe fittings used in transmission coolers. Its threads are tapered and designed to seat together tightly. NPT fittings require thread sealant as well as pipe dope and PTFE tape for proper thread engagement. AN fittings are identical to NPT fittings, except that they don’t require thread sealant.
NPT pipe threads are threaded so that the male thread crests are slightly smaller than the female thread crests. This clearance creates a spiral leak path along the male thread crests, which is why they need thread sealant. NPT fittings should be installed correctly and maintained properly to ensure their performance.
Although they are similar in purpose and construction, NPT and NPTF threads are ideal for fluid fittings. Both thread types use tapered threads to ensure tight connections. NPT connections are easily identified by measuring the thread diameters and subtracting 1/4″ from them. NPT threads are not perfectly smooth and are best suited to single-assembly applications. This is because frequent assembly and disassembly could cause thread wear.
When used correctly, NPT and NPTF transmission cooler fittings can prevent leaks from entering the transmission cooler. Threaded tapers create an interference fit between the thread-crests of the two threads. This tightens the seal and forces the threads into tight fitting. However, the threads of NPTF and NPT fittings are different, and they require careful tightening to ensure the proper seal. Leakage and other problems can be caused by improper tightening.
NPT fittings are used most often to connect transmission cooler lines. NPT threads are more resistant to pressure than NPS threads, and prevent leaks. When upgrading transmission cooler lines, NPT fittings are often recommended. The NPT threads are more flexible, which makes them easier to work with. They also have a greater sealing capacity than NPTS.
You can also use British threads in place of NPT. Unlike NPT, British threads are less common, but you can verify their integrity by following the same steps as for NPT. To confirm the dimensional accuracy of British threads, measure the O.D. The fitting should be done at three to four threads away from the end.
Hybrid hoses
Flexible tubes that transfer transmission fluid from an engine to an oil cooler or heat exchanger are called automatic transmission cooler hoses. These hoses can also carry lubricant to brake rotors and differentials. They are considered OEM (original equipment manufacturer) parts and are designed to be OEM-compatible, meaning that they are designed to fit your specific vehicle model.
