Technical data and material properties

NORRES BAGGERMAN's technical data sheets collect everything that comes before a concrete material choice: density, temperature ranges, mechanical properties, thread standards and IP classification. Use this page as a reference handbook when dimensioning a hose line — or download the PDF data sheets directly into your specification.

The technical reference handbook

Material selection for an industrial hose is about more than chemical resistance. Once the chemistry is settled — and the resistance table covers that — the mechanical, thermal and electrical properties still need to match the application. On this page we collect the four documents that together make up the technical reference handbook: two material property tables (Eigenschaftstabelle 1 and 2), Gewindenormen for fittings and couplings, and Eindringschutz CP for IP classification per EN 60529.

Four different hose cross-sections showing internal construction: spiral-reinforced plastic, antistatic hose with copper wire, rubber-based composite construction and mesh-reinforced transparent hose
Four different hose constructions: spiral-reinforced plastic, AS hose with visible copper wire, rubber composite structure and mesh-reinforced transparent hose — the choice of construction affects pressure, flexibility and electrical properties.

Material properties for 11 hose materials

NORRES BAGGERMAN's Eigenschaftstabelle 1 covers 11 plastic and rubber types in the main programme. The classification uses four levels: ++ excellent, + good, O limited and - poor. Table values apply at 20 °C unless otherwise stated. The 11 materials are:

MaterialAbbreviationDensity (g/cm³)Permanent temperature (°C)
Ester polyurethanePUR, TPU1.18-40 to +90
Ether polyurethanePUR, TPU1.11-40 to +90
Soft PVCPVC-P1.22-20 to +70
PolyethylenePE0.92-35 to +80
Thermoplastic rubberTPE-O0.98-40 to +125

TEFLON® (PTFE)PTFE2.15-200 to +250
PolyamidePA1.13-40 to +90

Eigenschaftstabelle 1 and 2 additionally cover tensile strength, elongation at tear, abrasion resistance and resistance against heat ageing, weathering, UV radiation, microorganisms, water, salt solutions, acids, alkalis, oxidising agents, solvents, mineral oil and petrol.

Thread standards — M, PG, NPT, UNEF, G

The Gewindenormen data sheet shows five international thread standards with correct standard references. NORRES BAGGERMAN's couplings and fittings are delivered to these standards depending on region and application:

M thread (Metric)

EN 60423, IEC 423 or BS 6053, ISO 68, DIN 13. M8–M63. Used in Europe as standard on PG-free cable installations.

PG thread

DIN 40430. PG7–PG48. Classic armoured gland thread — still used in older installations and as retrofit.

UNEF thread

ANSI/ASME B 1.1. 1/2", 5/8", 3/4", 7/8" and up. Precision thread with fine pitch — used in US and British installations.

NPT thread

ANSI/ASME B 1.20.1. 1/4" to 2". Tapered pipe thread — standard in the US for liquid and gas connections.

G thread (Whitworth-R)

JIS B 0204, DIN ISO 228-1 or BS 2779. G16–G54 (1/4"–2"). Cylindrical pipe thread — widely used globally on pipe fittings.

For the full table with precise diameters, pitch values and chain information per dimension, see the Gewindenormen PDF below.

IP classification per EN 60529

The IP (Ingress Protection) classification indicates how well an enclosure or assembly protects against ingress of solid particles and liquids. It is widely used on electrical components and hose couplings. The classification consists of two digits — the first indicates protection against solid particles (0–6), the second against liquids (0–9 / 9K).

First digit — solid particles

LevelEffective againstDescription
0No protection against contact or ingress of objects.
1Large solid particlesProtection against contact with large surfaces (back of hand). Solid particles Ø > 50 mm.
2Medium-sized solid particlesProtection against contact with fingers. Solid particles Ø > 12.5 mm.
3Small solid particlesProtection against tools, thick wires and small solid particles Ø > 2.5 mm.
4Very small solid particlesProtection against tools, most wires and very small solid particles Ø > 1 mm.
5Dust (limited)Complete contact protection. Protection against dust accumulation on the inside.
6Dust (dust-tight)Complete contact protection. Protection against ingress of dust.

Second digit — liquids

LevelEffective againstDescription
0No protection against ingress of water.
1Dripping waterProtection against vertically dripping water.
2Dripping water at angleProtection against dripping water at any angle up to 15° from vertical.
3Spraying waterProtection against spraying water up to 60° from vertical.
4SplashingProtection against water splashing from any direction.
5Water jetsProtection against directed water jets at low pressure from any angle.
6Powerful water jetsProtection against directed water jets at high pressure from any angle.
7ImmersionProtection against full immersion up to 1 metre depth.
8Long-term immersionProtection against long-term immersion under pressure — conditions specified by the manufacturer.
9 / 9KHigh-pressure cleaningProtection against high-pressure water jets at high temperature (up to 80 °C). Often used on vehicles and industrial cleaning.

In practice, the most common ratings on industrial hose fittings are IP65 (dust-tight and splash-protected), IP68 (dust-tight and long-term immersion) and IP69K (high-pressure cleaned).

Frequently asked questions about technical data and materials

Which 11 materials are covered by the Eigenschaftstabelle?

Ester-PUR, Ether-PUR, soft PVC, polyethylene (PE), thermoplastic rubber (TPE-O), NEOPRENE® (CR), HYP/CSM, VITON® (FKM), silicone (Q), TEFLON®/PTFE and polyamide (PA).

What do IP65, IP68 and IP69K mean?

IP65 = dust-tight and splash-protected. IP68 = dust-tight and long-term immersion under pressure. IP69K = protection against high-pressure water jets at high temperature (up to 80 °C). All classifications per EN 60529.

Which thread standard is most common in Europe?

M thread (metric) per EN 60423, IEC 423, ISO 68 and DIN 13. It is used as standard in Europe on PG-free cable installations.

What is the difference between G and NPT threads?

G (Whitworth-R) is cylindrical and widely used globally on pipe fittings. NPT (ANSI/ASME B 1.20.1) is tapered and standard in the US for liquid and gas connections. They are not directly compatible — adapters are required to cross between them.

What is PG thread, and is it still used?

PG (Panzergewinde) is the classic armoured cable gland thread per DIN 40430. It is still used in older installations and as retrofit, but new installations in Europe typically use M thread.

Which material has the widest temperature range?

PTFE (TEFLON®) with -200 to +250 °C permanent. It also has the widest chemical resistance — but lower mechanical wear resistance than PUR and is more expensive.

Where do I find the technical data for a specific hose?
