Description
Metal Flex Garden Hose
Product Overview
The Metal Flex Garden Hose is a corrugated stainless steel flexible hose supplied with threaded, flanged, or quick-connect ends. It is used in HVAC, water supply, fire protection, gas utility, irrigation, and equipment connection pipelines.
Core Advantages
1. Progressive bending without local kinking. The wave structure spreads bending strain along the hose rather than concentrating it at one point. In tight plant rooms and equipment skids, the hose can follow controlled direction changes without a sharp crease or local wall collapse.
2. Controlled pressure and tensile load. External restraint transfers axial force toward the end fittings instead of letting it stretch the corrugated core. The hose therefore holds its working length more consistently under pressure and vibration.
3. All-metal thermal stability. The metallic flow path remains non-combustible and dimensionally stable through rapid temperature changes. It does not soften or age in the same way as an elastomer hose.

Customization Capabilities
- The bellows can be produced in 304 or 316L stainless steel with the required diameter, length, corrugation profile, and PN6 to PN40 pressure rating.
- An unbraided or stainless-braided construction can be selected according to pressure and tensile load.
- End connections can be configured as flanges, male or female threads, quick connectors, or drawing-based fittings, with the required orientation.
Quality Control
Stainless material grade, wall thickness, corrugation pitch, and end-fitting dimensions are checked before welding. Welds are visually inspected, and the completed hose is proof-tested at 1.5 times design pressure. Gas-service units also receive air-tightness testing. Bend shape, braid coverage, end alignment, and overall length are verified before final cleaning and packing. Every hose is inspected before shipment. Third-party inspection is accepted.
FAQ
Q: How long does a custom hose take to produce?
A: Custom-made products normally require 40 to 50 days. A new sample normally takes 15 to 20 days after the end fittings and length are approved.
Q: How is the hose protected for shipping?
A: End fittings are capped, the hose is coiled above its minimum bend radius, and the assembly is fixed in a carton or wooden case to prevent crushing and abrasion.
Q: What is the minimum bend radius?
A: The minimum bend radius is specified for the ordered diameter and corrugation. The hose must not be bent tighter than that value during installation or operation.
Q: Can it absorb pipeline misalignment?
A: Yes. It absorbs controlled lateral and angular offset, but the hose must be installed without torsion and must not be used to force severely misaligned flanges together.
