When precision and reliability are critical, Crist Group’s PFA & FEP retractable coils and spray rinse assemblies provide the perfect solution. PFA (Perfluoroalkoxy) and FEP (Fluorinated Ethylene Propylene) are widely used in industries such as semiconductors, whose market size has been estimated to reach approximately USD 625.05 billion in 2023. Overall, the semiconductor market is expected to grow at a CAGR of 7.7% from 2024 to 2032 and reach approximately USD 1,2815.8 billion by 2032.

Retractable coils are highly versatile coiled hoses designed to deploy and retract as required for efficient fluid transfer in tight spaces. On the other hand, spray rinse assemblies are generally applied to high-purity cleaning processes, often used by semiconductor and health science industries. These products are engineered to handle corrosive chemicals and high temperatures with ease—features that make them essential for industries where standard materials simply won’t do.

Crist Group manufactures its retractable coils and spray rinse assembly from PFA and FEP, both of which are fluoroplastics comprising exceptional features. Here’s why they’re superior:

  • Chemical Resistance: PFA and FEP do not swell when exposed to harsh chemicals and are, therefore, best suited for application in semiconductor and drug manufacturing.
  • High-Temperature Tolerance: Being resistant to heat up to 260°C (500°F), these materials will effectively address both heat and cold applications without significant influence on efficiency.
  • Non-Stick Surface: Fluoroplastics are naturally resistant to materials, which keeps the fluids pure and avoids the accumulation of chemicals.
  • Flexibility and Durability: PFA and FEP retractable coils are flexible enough to work in restricted areas and very robust enough to endure daily usage in rigorous conditions.

Crist Group’s PFA and FEP retractable coils and spray rinse assemblies are versatile, finding applications in a variety of industries:

  • Semiconductor Manufacturing: Used in high-purity cleaning and fluid transfer systems, these coils and assemblies ensure contamination-free operations.
  • Pharmaceuticals & Health Sciences: PFA and FEP are chemically resistant and pure, which makes these products suitable for application in laboratories and medical facilities.
  • OEM & Automotive: Reliable, stretchy, and chemically corrosion-proof, they are utilized in flow control systems in the automobile industry.
  • Chemical Processing: These assemblies are very useful in transporting aggressive chemicals in processing plants, improving safe and efficient operations.

At Crist Group, we understand that one size doesn’t fit all. Our PFA and FEP retractable coils come in various diameters and lengths, designed to meet the unique demands of your specific application. Whether you need high-flow capacities or compact, flexible designs, our team can engineer the perfect solution. We also offer full customization options, including:

1. Size Adjustments:

Standard part diameters are ¼ inch to 1-inch diameter, but they can be manufactured in other specifications depending on the customer’s requirements.

2. Material Choices:

Select between PFA and FEP depending on the chemical and temperature resistance you desire for your product.

3. Fittings and Connections:

As for the connectors and fittings, we have a complete set to guarantee that you can connect them smoothly with your current systems.
