As all you sharp hose wizards know, when it comes to fluid transfer systems, the choice of hoses plays a crucial role in ensuring efficiency and safety. PTFE (Polytetrafluoroethylene, or Teflon) lined braided stainless steel hoses have gained immense popularity in numerous industries due to their exceptional attributes. They can handle all types of media, and have very high chemical and temperature resistance. In this blog post, we will explore five different attributes of PTFE lined braided stainless steel hoses and discuss the applications that are best suited for their use. Additionally, we will delve ( just a little bit ) into the differences between SAE 100R115 and SAE 100R14 hose specifications, shedding light on their unique features and applications.

1. Chemical Resistance: One of the primary advantages of PTFE lined braided stainless steel hoses is their outstanding chemical resistance. The PTFE lining acts as a barrier against a wide range of corrosive chemicals, making them ideal for applications in the chemical and pharmaceutical industries. These hoses are capable of withstanding harsh environments and maintaining their structural integrity, ensuring safe and reliable fluid transfer.

2. Temperature Resistance: PTFE lined braided stainless steel hoses exhibit remarkable temperature resistance properties. They can operate efficiently in extreme temperature conditions ranging from -100°C to +260°C (-148°F to +500°F). This wide temperature range allows for their use in applications that involve both high and low temperatures, such as in the automotive, aerospace, and industrial sectors. Braided stainless steel hoses are often selected for this attribute alone. He's heating up! *NBA Jam voice*

3. Non-Stick Surface: The non-stick properties of PTFE lining make these hoses highly desirable for applications involving viscous fluids, adhesives, or materials prone to clogging. The smooth inner surface of the hose prevents material buildup, ensuring consistent flow and minimizing the risk of blockages. Industries like food processing, cosmetics, and paint applications greatly benefit from this attribute. If it keeps that pork chop from sticking, it'll keep that cosmetic gunk from sticking to the hose liner!

4. Flexibility and Durability: PTFE lined braided stainless steel hoses are renowned for their flexibility and durability. The stainless steel braiding provides excellent mechanical strength, preventing kinks and damage during operation. Moreover, the PTFE lining offers exceptional resistance to wear, tear, and abrasion. This combination of flexibility and durability makes these hoses suitable for demanding applications in hydraulic systems, power steering, and other heavy-duty industrial applications.

5. Electrical Insulation: Another advantage of PTFE lined braided stainless steel hoses is their excellent electrical insulation properties. The non-conductive PTFE lining effectively insulates against electrical currents, making them ideal for applications in the electrical and electronics industries. These hoses are commonly used in applications requiring protection against electromagnetic interference (EMI) or radio frequency interference (RFI).

SAE 100R115 vs. SAE 100R14: While both SAE 100R115 and SAE 100R14 hose specifications pertain to PTFE lined hoses, they have distinct characteristics and applications. SAE 100R115 hoses are designed for high-pressure hydraulic systems and are reinforced with a single braid of stainless steel wire. They are commonly used in heavy machinery, construction equipment, and hydraulic systems where robust performance under high pressures is crucial.

On the other hand, SAE 100R14 hoses are known as "standard" or "true" PTFE hoses. They are specifically designed for low-pressure applications and are reinforced with multiple braids of stainless steel wire. SAE 100R14 hoses find their utility in a wide range of industries, including automotive, chemical, pharmaceutical, and food processing, where the focus is on chemical resistance, temperature stability, and non-stick properties. R114 Hose has a true bore ID, whereas R115 has a nominal ID.

In conclusion, PTFE lined braided stainless steel hoses offer a myriad of benefits that make them a preferred choice in various industries. Their exceptional chemical resistance, temperature stability, non-stick properties, flexibility, and electrical insulation. Plus they're shiny! Happy hosing you rascals.
