BSPP Full Socket - 316 Stainless Steel
150lb Class | EN 10241-1 | 40 Bar | 1/8" to 6"
Product Overview
This heavy-duty BSPP Full Socket provides a robust female-to-female connection for high-pressure pipe systems. Unlike standard cast fittings, this socket is **manufactured from 316 stainless steel pipe**, offering superior strength and material integrity. Adhering to EN 10241-1 medium weight dimensions and DIN 2986 standards, it features greater external dimensions than economic sockets, ensuring durability in demanding industrial, plumbing, and marine environments.
Rated for a maximum working pressure of **40 bar (600 psi)** and featuring BSPP parallel threads (ISO 228-1). Available in sizes from 1/8" to 6" (A socket weld version is also available).
Key Features
- Manufactured from 316 Pipe: Superior strength and material integrity compared to cast fittings.
- High Pressure Rating: Rated for up to 40 bar (600 psi) maximum working pressure.
- Premium 316 Stainless Steel: Excellent corrosion resistance for demanding applications and fluid compatibility.
- BSPP Female Threads: Parallel threads (ISO 228-1) on both ends for secure connection to male threaded fittings.
- Heavy Duty Dimensions: Conforms to EN 10241-1 (Medium Weight) & DIN 2986 for enhanced robustness.
- Versatile Application: Suitable for high-pressure water, oil, gas, chemical, and industrial systems.
- Wide Size Range: Available in sizes from 1/8" up to 6" BSPP.

Pressure-Temperature Rating
| Temperature (°C) | Maximum Working Pressure (Bar) |
|---|---|
| -20 to 100 | 40 |
| 150 | Approx 35* |
| 200 | Approx 30* |
| 220 | Approx 28* |
Max Pressure: 40 bar (600 psi) at ambient/low temperature.
*Pressure ratings decrease significantly at higher temperatures. The exact derating factor for 40 bar fittings depends on specific manufacturing details and standards followed beyond EN 10241 dimensionally. Consult specific manufacturer data or relevant pressure vessel codes (e.g., ASME B31.3) for precise high-temperature allowable pressures if critical for your application.
Note: Piping loads, stresses, and moments are not taken into account in these ratings.
