This is a fitting that converts to a vacuum flange NW25 with a hose connection (bamboo shoot).
Our company, Chūnichi Giken Kōgyō, is a manufacturer of stainless steel flexible tubes. Here we introduce a case study of a custom-made product. 【Case Study】 ■Product: Conversion Joint ■Specifications: A joint that converts to a vacuum flange NW25 + hose connection (bamboo shoot) ■Manufacturing Points: We received a request to attach a resin hose to a vacuum pump and connect an NW25 on the opposite side. Since there was a length specification, we processed and manufactured the hose connection ourselves. As this is not a standard product, we can manufacture it to your desired joint and length. ［Chūnichi Giken Kōgyō - Product Lineup］ Stainless steel flexible tubes, stainless steel expansion joint fittings, PTFE hoses, rubber joints, welded products ［About Us］ At Chūnichi Giken Kōgyō, we specialize in made-to-order production and can accommodate manufacturing from one piece.

Made of SUS316. It has a simple structure consisting only of the main body and bag nut. Despite being easy to tighten, it is a joint with good airtightness. Nipple, elbow, tee.
This is the standard for fittings for fluoropolymer (PFA, FEP, etc.) tubes. Made of SUS316, it is corrosion-resistant and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube breaks. For more details, please visit our company website.
This is a nipple fitting for a tube with an inner diameter of 1 mm. Made of SUS316. It has a simple structure consisting only of the main body and a bag nut. Despite being easy to tighten, it is airtight.
We have standardized fittings to meet the needs for 1mm inner diameter (3X1) tubes. They can be applied to silicone tubes and fluoropolymer (PFA, FEP, etc.) tubes. However, for fluoropolymer tubes, the pipe ends need to be slightly enlarged for installation. Made of SUS316, they are corrosion-resistant and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube fails. *For more details, please contact us.*
The M5 screw joint for 4X2 tubes has been made super compact. Made of SUS316. It has a simple structure consisting only of the main body and the bag nut, making tightening easy.
It has been developed to meet the needs for compactness. Currently, it is classified as a non-standard product. Made of SUS316, it has corrosion resistance and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube breaks. *For more details, please contact us.*

This product was developed in response to the need to connect stainless steel pipes and plastic tubes by welding fittings to the ends of the stainless steel pipes. The plastic tube attachment part is the same as our standard stainless steel fittings. Made of SUS316, it is corrosion-resistant and can be used over a wide temperature range from high to low temperatures. There are no abnormalities in the fittings until the tube fails. *For more details, please contact us.
This is a non-standard female screw fitting made of SUS316. It has a simple structure consisting only of the main body and a bag nut.
We developed this in response to the needs for female screw specifications. We will actively accommodate even non-standard requests. It is a joint that is easy to tighten yet has good airtightness. *For more details, please contact us.
No welding required at the pipe inlet and outlet! The panel union is screw-fastened, making it easy to create pipe inlets and outlets, contributing to cost reduction.
In machinery and equipment, it is common practice to weld pipe components to the plates of panels or housings at the inlet and outlet of piping, but this is a labor-intensive task. With a panel union, you simply pass it through a hole in the plate and screw it in place. Since it is clamped with a spring washer, there is no worry about it loosening. By installing it on a thin wall that cannot have screw holes cut, you can form a joint for other threaded piping. There are no screw holes. There is not enough thickness to cut screw holes. There is not enough strength to cut screw holes. You are welding round bars or Rc union fittings just to create screw holes. There are places where you want to secure R threads. We can solve these concerns. *For more details, please contact us.
With the liquid connection part PFA, attaching and detaching fluoropolymer (PFA, FEP, etc.) tubes is a one-touch operation! It is faster than conventional fluoropolymer fittings could ever imagine. Patent pending.
Traditionally, fluororesin fittings did not have a one-touch type; all were of the screw type, requiring sleeves and often necessitating pre-processing of the ends of fluororesin tubes using tools, which has been considered quite labor-intensive. We challenged this common understanding and, based on years of experience and knowledge, conducted thorough examinations to finally realize an all-resin one-touch fitting with a PFA liquid-contact part. Currently, we are promoting performance evaluations with users and responding to customer requests through made-to-order production. *For more details, please contact us.*
Connector for ultra-fine tubes with an inner diameter of 0.5 mm! Developed using PEEK material, but other materials are also possible. Please consult us!
We developed this in response to the request, 'The tube dimensions are too small, and there are no suitable fittings. Is there anything that can be done?' The fitting has a simple structure consisting only of the main body and the bag nut. Despite being easy to tighten, it has good airtightness, and there are no abnormalities in the fitting until the tube breaks. *For details, please contact us. We also accept orders for ultra-thin tubes.
