DKM 90° or WNP90 elbow fitting 

Elbow fitting with internal thread and 60° spherical cone. 

90 elbow fitting ( bent at a 90-degree angle ) spherical works with seat 60 according to DIN 7631 and DIN 7647. This fitting, also known as Russian, unlike metric fittings which have a 24-degree cone, this one has a 60-degree cone ( ball ). The 60-degree cone looks identical to the DKR fitting ( identical to the BSP inch fitting. WNP / DKM fittings can be found in equipment of Eastern European production ( Belarus, Russia, Ukraine ) they occur among others in MTZ, BELARUS equipment. In Poland, this type of fitting is designated as a P62 or H62 fitting.

WNP90 hydraulic fittings° with a 60° spherical cone.

WNP90 fittings, also known as Russian fittings, are specialized hydraulic components designed for crimping on hydraulic hoses. They are characterized by a spherical cone with a 60° angle, which distinguishes them from standard metric fittings with a 24° cone. They come in two variants: straight (WNP) and 90° elbow (WNP90). Shape: WNP (P61/H61): Straight fitting with a 60° spherical cone. WNP90 (P62/H62): 90° elbow fitting bent at a 90° angle with a 60° spherical cone. Thread: Metric, compliant with DIN 7631 and DIN 7647 standards. Material: Made of high-quality free-cutting steel with a zinc coating, ensuring corrosion resistance. Sealing: 60° spherical cone, working with a 60° seat according to DIN 7631 and DIN 7647 standards.

Application of WNP elbow fittings

WNP and WNP90 fittings are commonly used in hydraulic systems of machines from Russia, Belarus, and other Eastern European countries. They are used to connect hydraulic hoses in high-pressure systems, ensuring the leak-tightness and reliability of connections. Industries: Power hydraulics: Drive and control systems in industrial machinery. Agriculture: Agricultural equipment requiring reliable hydraulic connections.
