The nut and sleeve are made of stainless steel (standard product). You can choose from three types of included sleeves: - Short tube type (6.35mm, 9.53mm, 12.7mm) - VCR male thread type - NPT male thread type Gasket material: choose from Teflon or nickel. Additionally, as an option, you can select the sleeve material from nickel, Hastelloy, Monel, or cast iron, and the sleeve can be delivered after EP treatment. All products are washed with pure water before shipment and oxygen is injected before sealing.

• Other physicochemical equipment

This is a connection joint for GFP's DISS. It has a proven track record of adoption by major semiconductor manufacturers and specialty gas manufacturers. The gas connection part uses reliable VIM VAR material (for SUS specifications). The standard is that the inner surface is treated with EP processing. The roughness is SUS specifications with Ra 0.25um or less. Before shipment, all products are inspected in a Class 100 clean room and are packaged in double plastic wrapping. 【Features】 ■ Proven track record of adoption by major semiconductor manufacturers and specialty gas manufacturers ■ The gas connection part uses reliable VIM VAR material (for SUS specifications) ■ The standard is that the inner surface is treated with EP processing.

Seamless EP pipes made of Japanese SUS316L with excellent internal smoothness and dimensional accuracy. We offer various sizes with outer diameters ranging from 6.35 mm to 12.7 mm. Additionally, please consider Kuroiwa Stainless for BA pipes, high-pressure fittings, and other clean piping materials.

• Piping Materials

All products fit perfectly into tubes of each size. All items are barrel polished, so there are no burrs, preventing gloves from tearing during work in clean rooms. Additionally, the glossy surface allows for cleaner piping arrangements.

This is a plug-in welded joint developed for small diameter sizes. By minimizing the tolerance with the tube and creating a WELD LINE that allows anyone to easily and reliably perform welding, it enables the construction of a leak-free (after passing leak tests) and clean piping system using TIG to weld the WELD LINE without the need for welding rods. It is particularly suitable for high-purity piping for toxic, flammable, semiconductor gases, vacuum, fuel cells, and scientific instruments, where tightening methods may not provide sufficient safety. It is undoubtedly helpful in reducing piping time. Product shapes: elbow, tee, cross, sleeve, cap, reducer sleeve, reducer tee, reducer elbow, etc. Dimensions: 3.18 mm to 25.4 mm Minimum order quantity: from 1 piece *We ship anywhere in the country! (We also ship overseas)
