DKR BSP 3/4" Plug – Swivel nut cap with 60° cone for external thread

The BSP DKR 3/4" plug is a professional sealing element designed for safe, permanent, or temporary closure of the working medium flow in power hydraulics systems. The cap is used for installation on hose ends and male socket connections equipped with an external cylindrical thread. The design, utilizing a swivel nut and a 60° internal sealing cone, ensures absolute airtightness of the connection under high working pressure and peak pressure surges. The product is widely used in construction and agricultural machinery, industrial equipment, and stationary power units. Precise manufacturing from carbon steel protected by a durable zinc coating guarantees optimal protection against corrosion in harsh environmental conditions.

Application and technical characteristics

The DKR BSP 3/4" cap is mounted directly onto male BSP external threads (G 3/4") with a 60° cone seat. The sealing process occurs as a result of mechanical compression of the conical surfaces (metal-to-metal connection), which eliminates the need for additional tape sealants or oakum. The component is characterized by very good mechanical resistance and pressure stability in circuits with a high frequency of work cycles.

Basic parameters and technical properties include:

Sealing standard: Compliant with BS 5200 / ISO 8434-6 with a 60° internal cone.
Pressure resistance: Safe operation in systems under working pressure up to 310 bar (31 MPa).
Media compatibility: Mineral oils, synthetic oils, glycols, water, and water-oil emulsions used in drive systems.
Surface protection: Passivated zinc coating protecting the component from moisture and chemical factors.
Assembly ergonomics: The freely rotating DKR nut facilitates installation in hard-to-reach places without the need for axial rotation of rigid lines. When modifying or expanding supply paths, it may also be useful to use hydraulic elbows.

Why choose HYDRON components?

HYDRON provides proven power hydraulics components manufactured in accordance with strict European industry standards. Each plug undergoes quality control regarding dimensional tolerance of threads and cone seat geometry, which completely prevents leaks in high-pressure systems. By choosing HYDRON products, you gain confidence in the precise fit of components and the trouble-free operation of the installation under variable loads. We encourage you to familiarize yourself with our offer for flexible hydraulic hoses and control elements such as hydraulic valves.

Frequently Asked Questions (FAQ)

How to correctly install the DKR BSP 3/4" plug?

The plug should be screwed manually onto the external thread until a clear resistance of the conical surfaces meeting is felt. Then, using a flat wrench, tighten the nut by the recommended angle or with the correct torque for the 3/4" BSP size. Proper compression of the 60° cone guarantees full tightness without the risk of damaging the thread.

Is Teflon tape or glue required for mounting the DKR plug?

No. DKR-type connections use a conical seal (60° cone), creating a tight fit at the metal-to-metal contact. Using Teflon tapes, oakum, or chemical sealants on the thread is a technical error that prevents the cone from seating properly in the socket and leads to leaks.

Is the DKR 3/4" cap reusable?

Yes, the plug with a DKR swivel nut is suitable for repeated assembly and disassembly, provided that the sealing cone surface and threads have not been mechanically damaged or overloaded with too much tightening torque during previous use.
