Exploring the Multiple Connection Types of DIN Banjo Fittings: From BSPP to Metric Threads

1. BSPP Male Thread with Metal Sealing
One of the most common connection types for DIN Banjo fittings is the BSPP male thread with metal sealing. This type of connection utilizes a parallel thread design that mates with corresponding BSPP female threads. The metal sealing element ensures a tight, leak-proof seal, making it ideal for high-pressure applications.

2. BSPP Male Thread with Soft Seal Ring
For applications that require a more flexible sealing solution, DIN Banjo fittings are also available with BSPP male threads equipped with soft seal rings. These soft seal rings, made from materials like rubber or silicone, provide a reliable seal while accommodating minor misalignments or surface imperfections. This feature makes them suitable for applications where installation conditions may vary.

3. Male Metric Thread with Soft Seal Ring
In addition to BSPP threads, DIN Banjo fittings also come with male metric threads, often paired with soft seal rings. Metric threads are widely used in international standards and are thus compatible with a broad range of equipment and components. The combination of metric threads and soft seal rings offers a versatile and reliable connection option for cross-border projects and multinational supply chains.

4. EO 24° Cone End Connection
Another unique connection type found in DIN Banjo fittings is the EO 24° cone end. This type of connection utilizes a tapered cone design that mates with a corresponding female cone socket. The 24° taper angle provides a strong and secure seal, making it suitable for high-pressure and high-temperature applications. EO 24° cone end connections are also known for their ability to accommodate thermal expansion and contraction, reducing the risk of leaks.

5. BSPP Male Stud with Metal or Soft Seal Ring
DIN Banjo fittings also offer BSPP male studs with either metal or soft seal rings. These studs provide a threaded connection point that can be tightened using a nut or similar fastener. The inclusion of metal or soft seal rings ensures a reliable seal, while the stud design allows for easy installation and adjustment.

6. Male BSP Thread and Male Metric Thread without Specific Seal Types
While not as common as the aforementioned connection types, DIN Banjo fittings are also available with male BSP and male metric threads without specified sealing elements. In these cases, the sealing method is often left to the discretion of the user, who may choose to employ additional sealing materials or gaskets as needed.
