2. Understanding Layflat Hose Sizes & Their Technical Parameters

Layflat hose sizes are defined mainly by their inner diameter (ID), wall thickness, and overall working/burst pressure. Selection of appropriate layflat hose sizes is critical to ensuring safe operation within your hydraulic systems. Standards often referenced include:

DIN 14811 (for firefighting hose dimensions)
ISO 7751 (general hose tolerances and burst/working pressure)
ANSI/NSF 61 (potable water safe hoses)

Below is a comprehensive layflat hose sizes comparison table, showing popular dimensions, specifications, and typical use-cases:

Nominal Size (inches/mm)	Inner Diameter (mm)	Wall Thickness (mm)	Working Pressure (bar/psi)	Burst Pressure (bar/psi)	Typical Application
1” (25mm)	25	1.4	5 / 72.5	15 / 217.5	Gardening, Drip Irrigation
2” (51mm)	51	1.5	6 / 87	18 / 261	Sump Pump Lay Flat Discharge Hose
3” (76mm)	76	1.7	8 / 116	24 / 348	Construction Water Supply
4” (102mm)	102	2.0	10 / 145	30 / 435	Firefighting/Municipal
6” (152mm)	152	2.5	10 / 145	30 / 435	Large Water Transfer
8” (203mm)	203	2.9	8 / 116	24 / 348	Flood/Disaster Relief

7. FAQ: Layflat Hose Sizes, Materials, Installation & Performance

Q1: What are the standard layflat hose sizes available?

A1: Standard inner diameters range from 1” (25mm) to 12” (305mm). The most common layflat hose sizes are 2” (51mm), 3” (76mm), 4” (102mm), 6” (152mm), and 8” (203mm). Customized diameters are available per project.

Q2: What is the recommended material for extreme abrasion or chemical media?

A2: For harsh chemicals or abrasive environments, TPU layflat hoses are superior—offering excellent hydrolysis, oil, and abrasion resistance. All materials meet ISO/FDA requirements for safety.

Q3: How is wall thickness related to pressure performance?

A3: Thicker walls allow for higher working/burst pressures (as per ISO 7751). For instance, a 2.5mm wall can reach 15 bar working, versus 1.4mm rated for 5-6 bar.

Q4: How are couplings installed and what international standards apply?
