Western Enterprises Cryogenic Transfer Hose—48 Inches
The Western Enterprises WMH-2-14 Cryogenic Transfer Hose is designed for safe nitrogen and argon transfer. It is cleaned for oxygen service and offers exceptional flexibility to maneuver in tight spaces. The hose resists kinking, which helps maintain stable flow during purging or gas sample transfers. Machined CGA stainless steel end connections ensure a secure, leak-resistant interface with compatible tanks and regulators. This hose combines reliable performance with durability for long-term use in laboratory, welding, or industrial environments.
RX WELD Inert Gas Hose—6.56 Ft Argon Flow
RX WELD’s 6.56-foot inert gas hose is built for consistent argon flow with two 5/8″ UNF-18RH fittings on each end. It supports up to 300 PSI working pressure and 900 PSI burst pressure, making it suitable for welding, purging, and inerting tasks. The hose’s flexible design helps minimize handling noise and kinks during operation. Its robust exterior and compatible fittings support reliable nitrogen or argon transfer in small to mid-size setups.
RX WELD Nitrogen Regulator With Hose
This RX WELD nitrogen regulator kit includes a regulator with a 5-foot refrigeration hose and a CGA580 inlet. It features a 0-4000 PSI input range and an adjustable output up to 450 PSI, with a gauge display that can read up to 600 PSI. The 2-inch protective gauge boots help protect the readings in industrial settings. It is designed for HVAC purging, inertization, pressure tests, and leak tests, delivering controlled nitrogen flow to support precision work.
RX WELD Inert Gas Hose—30 Ft Argon Flow
The RX WELD 30-foot inert gas hose offers extended reach for larger purging or welding stations. With 5/8″ UNF-18RH fittings on both ends, it maintains stability under higher-flow conditions. The 300 PSI working pressure and 900 PSI burst pressure provide a solid margin for most inert gas tasks, including nitrogen purging and argon-based welding operations. Its length helps cover larger workspaces while preserving flexibility for routing around equipment.
Kegconnection Gas/Air Hose, 13 Ft
The Kegconnection 13-foot gas/air hose is made in the USA and features a dual-layer design to resist kinking and abrasion. It is marketed for CO2, nitrogen, or other inert gas applications. The hose is thick-walled to reduce permeation and leaks, providing stable delivery for purging, leak testing, and carbonation-related tasks in beverage or lab environments. The dual-layer construction supports long service life in demanding settings.
Buying Guide
When selecting a flexible nitrogen gas hose, consider the following factors to match your specific use case:
- Material and cleanliness: For nitrogen, hoses cleaned for oxygen service and made from compatible materials minimize contamination in sensitive operations.
- Pressure rating: Match working and burst pressures to your system; higher PSI ratings provide a safety margin for purging and testing.
- End fittings and compatibility: Ensure the hose ends use standard 5/8″ UNF-18RH or CGA580 interfaces for regulators and tanks you own.
- Length and flexibility: Shorter hoses reduce dead volume, but longer hoses enable greater reach. Consider your workspace layout and routing needs.
- Braided vs. flexible walls: Dual-layer or thick-walled hoses offer durability in industrial environments; select based on abrasion resistance and handling.
- Temperature and chemical resistance: Cryogenic-rated hoses handle very low temperatures, while standard inert gas hoses are adequate for typical purging and welding tasks.
- Regulation and control: If precise flow is critical, opt for hoses paired with regulated flowmeters or regulators that provide stable, adjustable output.
- Brand and support: Choose reputable brands with available replacements and compatibility notes for common inert gas operations.
In practice, your choice balances length, pressure requirements, and the environment. For tight workshop spaces, a shorter, kink-resistant hose with robust fittings often yields the most reliable performance. For larger laboratories or fabrication bays, longer hoses paired with a reliable regulator and gauges provide the flexibility needed to manage multiple stations efficiently.
