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.
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:
| Material | Abbreviation | Density (g/cm³) | Permanent temperature (°C) |
|---|---|---|---|
| Ester polyurethane | PUR, TPU | 1.18 | -40 to +90 |
| Ether polyurethane | PUR, TPU | 1.11 | -40 to +90 |
| Soft PVC | PVC-P | 1.22 | -20 to +70 |
| Polyethylene | PE | 0.92 | -35 to +80 |
| Thermoplastic rubber | TPE-O | 0.98 | -40 to +125 |
| NEOPRENE® | CR | 1.23 | -50 to +150 |
| HYP (=CSM) | CSM, PEC | 1.27 | -40 to +170 |
| VITON® | FKM, FPM | 1.80 | -20 to +210 |
| Silicone | Q | 1.15–2 | -70 to +260 |
| TEFLON® (PTFE) | PTFE | 2.15 | -200 to +250 |
| Polyamide | PA | 1.13 | -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
| Level | Effective against | Description |
|---|---|---|
| 0 | — | No protection against contact or ingress of objects. |
| 1 | Large solid particles | Protection against contact with large surfaces (back of hand). Solid particles Ø > 50 mm. |
| 2 | Medium-sized solid particles | Protection against contact with fingers. Solid particles Ø > 12.5 mm. |
| 3 | Small solid particles | Protection against tools, thick wires and small solid particles Ø > 2.5 mm. |
| 4 | Very small solid particles | Protection against tools, most wires and very small solid particles Ø > 1 mm. |
| 5 | Dust (limited) | Complete contact protection. Protection against dust accumulation on the inside. |
| 6 | Dust (dust-tight) | Complete contact protection. Protection against ingress of dust. |
Second digit — liquids
| Level | Effective against | Description |
|---|---|---|
| 0 | — | No protection against ingress of water. |
| 1 | Dripping water | Protection against vertically dripping water. |
| 2 | Dripping water at angle | Protection against dripping water at any angle up to 15° from vertical. |
| 3 | Spraying water | Protection against spraying water up to 60° from vertical. |
| 4 | Splashing | Protection against water splashing from any direction. |
| 5 | Water jets | Protection against directed water jets at low pressure from any angle. |
| 6 | Powerful water jets | Protection against directed water jets at high pressure from any angle. |
| 7 | Immersion | Protection against full immersion up to 1 metre depth. |
| 8 | Long-term immersion | Protection against long-term immersion under pressure — conditions specified by the manufacturer. |
| 9 / 9K | High-pressure cleaning | Protection 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?
