PYROFLAT
PYROFLAT is a highly flexible layflat firefighting hose with EPDM lining and polyurethane-coated red outer coating. The hose is wear-resistant, UV-resistant and seawater-resistant, making it suitable for marine firefighting installations and coastal facilities. The operating range -40 to +80 C with pressure rating 12-20 bar (depending on dimension) and burst pressure 30-50 bar. 5 standard firefighting dimensions (ID 38, 52, 65, 75, 102 mm) with 50 m standard roll length. Typically used in fire brigades, municipal disaster services, marine firefighting and industrial fire installations.

Why this hose?
Saltwater resistance is a distinctive feature in PYROFLAT. EPDM and polyurethane are both specific materials that resist salt exposure better than NR (natural rubber) or SBR typically used in standard fire hoses. This makes PYROFLAT suitable for marine and coastal installations where other fire hoses would have significantly shorter service life.
PU-coated outer coating protects against sharp edges and hot surfaces. Firefighting hoses are often dragged over building materials, glass shards and hot surfaces - a standard rubber coating would quickly wear or burn. The PU coating resists these impacts and extends the hose's functional service life.
The layflat construction's 50 m standard roll typically covers an entire firefighting installation. Unlike round-shaped hoses (which always occupy physical volume), a 50 m layflat hose can be stored as a compact coil under 1 m diameter - critical for fire brigades where multiple hoses must be stored on vehicles with limited space.
Where it is used
Municipal fire brigades use the hose as primary fire hose on fire vehicles. A typical configuration has 100-200 m of PYROFLAT in various dimensions (38, 52, 65, 75 mm) for different fire scenarios. The red outer coating makes the hose immediately recognisable in emergency situations.
Marine and port facilities use the hose in fixed-installed firefighting systems on ships, quays and oil tankers. Saltwater resistance is critical here - standard fire hoses would have markedly shorter service life in marine exposure, and PYROFLAT is a pragmatic solution for these installations.
Industrial fire systems at chemical facilities, refineries and large construction sites use the hose for mobile and stationary firefighting installations. Pressure rating 20 bar with 50 bar burst margin is plenty for high-pressure fire pump applications, and UV resistance allows the hose to be exposed outdoors throughout the year.
The hose is colloquially known as a firefighting hose, fire hose or PYROFLAT firefighting hose.

Industries that use it
PYROFLAT is used in firefighting and disaster control installations where the hose must tolerate sharp-edged objects, UV exposure and seawater - typically in municipal fire brigades, marine installations and industrial fire systems.
Municipal fire brigades are the main market. Fire vehicles equipped with PYROFLAT in multiple dimensions (38-102 mm) can handle all typical fire scenarios - from house fires with 38 mm hoses to large industrial fires with 102 mm main supply hoses. The layflat construction is practical for compact storage on vehicles.
Marine and coastal facilities use the hose for firefighting installations where saltwater exposure is a reality. The EPDM lining and PU-coated outer coating both resist salt spray and direct saltwater, significantly extending the hose's service life compared to standard fire hoses.
Industrial and municipal disaster control services use the hose in mobile firefighting stations and fixed-installed fire systems. UV resistance is particularly valuable because the hoses are often exposed to sunlight on outdoor-mounted reels or transport vehicles.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll can be supplemented with shorter pieces or multiple rolls by arrangement.

Frequently asked questions
What is PYROFLAT particularly suitable for?
PYROFLAT is a specialised layflat firefighting hose with EPDM lining and polyurethane-coated outer. The hose is wear-resistant and UV-resistant, making it suitable for firefighting and disaster control installations where the hose may be exposed to sharp-edged objects, hot surfaces and UV exposure. Working pressure 12-20 bar with 30-50 bar burst pressure depending on dimension.
What makes the hose seawater-resistant?
EPDM lining and PU-coated outer coating are both resistant to salt water. This makes the hose suitable for marine firefighting installations on ships, port facilities and coastal installations where saltwater is a reality. Standard NR (natural rubber) firefighting hoses would degrade faster under salt exposure.
How many dimensions are in the range?
5 dimensions: ID 38, 52, 65, 75 and 102 mm - all standard firefighting dimensions. Pressure falls gradually with dimension: 20 bar on 38-75 mm, and 12 bar on 102 mm. Burst pressure is 50 bar on small dimensions and 30 bar on 102 mm. 50 m standard roll length across the range.
Is the hose flame-retardant?
The hose is specifically designed for firefighting - it leads water TO the fire, not away from it. The polyurethane-coated outer surface is wear-resistant against sharp edges and hot surfaces, but is not specifically fire-classified per EN 13501-1 or NF P 92-503. For fire applications where the hose is directly exposed to flames we recommend a specialised fire-resistant hose.
What does 'layflat' construction mean?
Layflat means the hose collapses flat in empty state and rounds up when water passes. This is a compact storage solution - 50 m of hose can be rolled to a coil under 1 m diameter, which is critical for fire brigades where multiple hoses must be stored on vehicles. The 'flat' measurement shows the hose's flat width in compressed state.
Which couplings are recommended?
For firefighting applications, Storz couplings (typically Storz B for 75 mm, Storz C for 52 mm) which are industry standard for fire brigades in Europe are recommended. The couplings snap together quickly without threads and provide pressure-tight connection. We fit couplings to the hose by arrangement.
What colour is the hose?
Black EPDM inner tube and red outer coating with 2-ply twisted polyester fabric. The red colour is international convention for firefighting hoses - a visual marker making the hose immediately recognisable in emergency situations. The red colour is also practical in that it contrasts against soil and asphalt backgrounds.
How long does a firefighting hose last?
PYROFLAT's EPDM/PU construction has long service life - typically 10-15 years in normal storage and occasional use. Firefighting hoses are typically replaced after visual inspection during annual maintenance on fire brigade vehicles. UV resistance is particularly valuable because the hoses are often exposed to sunlight on the vehicles' reels.
