1/4 inch VCR Female Male Bellow Hose Coupling – KNvss Stainless Steel

Description

Product Overview

The KNvss 1/4 inch VCR female‑male bellow hose coupling is engineered for precision‑fit applications where reliability and flexibility are paramount. Constructed from SUS316 grade stainless steel, the component resists corrosion, high‑temperature exposure, and chemical attack, making it suitable for demanding industrial and scientific environments. The coupling features a compact, one‑size design that integrates seamlessly with standard pipe fittings, while the 0.25‑inch (1/4″) thread provides a secure, leak‑free seal.

Designed with a flexible bellows section, the hose accommodates slight misalignments and vibration without compromising the integrity of the connection. This flexibility reduces stress on adjoining equipment, extending the service life of both the coupling and the connected system. The lightweight construction—only 50 grams—facilitates easy handling during installation and maintenance, yet the robust material ensures long‑term durability.

Key specifications include a one‑size universal fit, stainless steel SUS316 composition, and a compact package measuring 1.18 x 0.79 x 0.39 inches. The product is certified for vacuum and semiconductor use, meeting industry standards for leak‑tight performance. Its sleek metallic finish not only provides aesthetic appeal but also contributes to easy cleaning and sterilization, essential for cleanroom and laboratory settings.

Overall, the KNvss coupling delivers a balance of strength, flexibility, and ease of use that addresses the critical needs of engineers, technicians, and researchers who demand high‑quality fluid handling components.

Usage

This coupling excels in vacuum systems, semiconductor processing lines, and any application requiring precise fluid control. Its stainless steel construction makes it ideal for handling corrosive gases, inert gases, and ultra‑pure liquids commonly found in laboratory and manufacturing environments. The flexible bellows allow the coupling to absorb thermal expansion and mechanical vibration, ensuring a stable connection even under fluctuating temperature conditions.

Typical installation scenarios include connecting flexible tubing to rigid pipework in vacuum chambers, linking gas delivery lines in semiconductor fab equipment, and integrating with pneumatic or hydraulic circuits where space constraints demand a compact solution. The 0.25‑inch thread matches standard fittings, simplifying inventory management and reducing the need for additional adapters.

End users range from process engineers in semiconductor fabs to maintenance technicians in research laboratories. The coupling’s lightweight nature enables quick replacement during scheduled downtime, minimizing system interruption. Its compatibility with a wide range of fluids and gases makes it a versatile component for both prototype development and full‑scale production.

FAQ

What types of fluids can this coupling handle?

The coupling is suitable for a wide range of gases and liquids, including inert gases, corrosive gases, ultra‑pure water, and organic solvents. Its SUS316 stainless steel construction resists chemical attack, making it appropriate for most industrial and laboratory fluids.

Is the coupling compatible with high‑temperature applications?

Yes. SUS316 stainless steel maintains its mechanical properties at elevated temperatures up to approximately 800 °F (427 °C). This makes the coupling suitable for processes that involve heat‑intensive operations, provided the temperature does not exceed the material’s rating.

How do I install the coupling to ensure a leak‑free seal?

Begin by cleaning the mating threads on both the coupling and the adjoining fitting. Apply a compatible thread sealant if required by the system specifications. Thread the coupling clockwise until hand‑tight, then use a calibrated wrench to achieve the recommended torque (typically 15‑20 Nm). Verify the seal by performing a pressure test before full system operation.

Can I use this coupling in cleanroom environments?

Absolutely. The smooth stainless steel surface is easy to clean and sterilize, meeting the stringent cleanliness standards of ISO 14644‑1 cleanrooms. It does not out‑gas or shed particles, ensuring it will not contaminate sensitive processes.

What warranty does KNvss provide for this product?

KNvss offers a one‑year limited warranty covering material defects and workmanship. If any issue arises within the warranty period, contact our support team for a replacement or repair, subject to the terms and conditions outlined in the warranty documentation.
