Threaded plastic blanking plug / cap M22x1,5

The threaded plastic blanking plug M22x1,5 is a protective cap designed for temporary securing of holes and hydraulic connections equipped with a compatible M22x1,5 female thread. The product is made of plastic and helps protect hydraulic hoses, manifolds, cylinders, valves, and other components from dust, dirt, metal shavings, and contamination during repairs, transport, storage, and assembly.

The plastic M22x1,5 cap has a metric male thread with a nominal diameter of 22 mm and a pitch of 1,5 mm. It allows for temporary closure of a properly matched hole until the final hydraulic connection is made. It is useful during hose replacement, equipment maintenance, and preparing spare parts for storage or shipping.

Important: the M22x1,5 plastic blanking plug does not withstand pressure loads. It must not be used to close hydraulic or pneumatic systems operating under pressure.

Color information: the product is available in various colors, packed and shipped randomly. The color of the delivered plug may differ from the one shown in the photo.

Nominal thread diameter: 22 mm.
Thread pitch: 1,5 mm.
Standard metric thread profile angle: 60°.
Material: plastic.
Intended use: temporary protection of threaded holes and connections.

Color: various colors, randomly packed.
Application: securing hoses, manifolds, cylinders, and other hydraulic components.

Application of the M22x1,5 protective cap in power hydraulics

The M22x1,5 plastic cap is used for temporary protection of open connections during service work, technical inspections, hydraulic hose replacement, and machine maintenance. It can be used in compatible ports of manifolds, cylinders, valves, and other elements equipped with an M22x1,5 female thread.

The blanking plug is useful during the disassembly of agricultural, construction, and industrial machine components. It helps reduce the risk of contamination entering the connection before the element is reconnected to the system.

M22x1,5 metric thread – dimensions and identification

The M22x1,5 designation specifies a metric thread with a nominal diameter of 22 mm and a pitch of 1,5 mm. The standard ISO metric thread has a triangular profile with a 60° angle. In the case of a protective blanking plug, the male thread is intended to work with the corresponding female thread of the connection being secured.

The M22x1,5 thread must be distinguished from other metric threads with a similar diameter but a different pitch. For example, the M22x1,5 thread is not interchangeable with M22x1 or M22x2. Incorrect selection may lead to damage to the plastic cap or the connection thread.

To identify the thread, a caliper and a metric thread pitch gauge can be used. Before assembly, check the thread diameter and pitch, as well as the condition of the threaded surface.

Protection of hydraulic hoses against contamination

During the disassembly of hydraulic systems, open hoses and connections are exposed to contact with dust, dirt, sand, and metal shavings. The M22x1,5 plastic blanking plug allows for the temporary closure of a compatible hole, helping to limit the access of contaminants to its interior.

Maintaining the cleanliness of hydraulic components is important for the durability and proper operation of the system. Contaminants entering the hydraulic oil can accelerate the wear of pumps, valves, manifolds, and sealing elements. Securing disconnected connections helps to reduce this risk.

M22x1,5 blanking plug for transport and storage

The M22x1,5 plastic cap is used during the transport and storage of hydraulic parts. Temporary closure of a threaded hole helps protect the interior of the component from dust and accidental entry of foreign objects.

The product can be used in power hydraulics workshops, spare parts warehouses, and during the preparation of components for shipping. The blanking plug serves as protection for the time when a given element is not connected to an operating system.

Plastic – construction of the protective cap

The M22x1,5 blanking plug is made of plastic. Its primary task is the temporary protection of threaded holes during transport, storage, assembly, and service work.

The plastic body is not intended to withstand pressure loads. During assembly, avoid excessive tightening, which could cause damage to the thread or deformation of the blanking plug.

Plastic blanking plug M22x1,5 vs. hydraulic pressure plug

The M22x1,5 plastic cap is used for temporary protection of connections against contamination. It is not designed to maintain working pressure and cannot replace a properly selected hydraulic pressure plug.

If the connection is to remain closed during the operation of the device, a suitable hydraulic plug with confirmed operating parameters, the correct thread, and an appropriate sealing method must be used. Just matching the M22x1,5 thread does not mean that the plastic blanking plug is suitable for pressure operation.

How to choose an M22x1,5 plastic blanking plug?

Before purchasing, check whether the hole to be secured has a compatible M22x1,5 female thread. The basic selection parameters are a nominal diameter of 22 mm and a pitch of 1,5 mm. Also, check the condition of the thread and the available assembly space.

The product is intended for temporary protection of connections during repairs, transport, and storage. It cannot be used as a closure for a hydraulic system operating under pressure.

Installation and removal of the M22x1,5 plastic cap

Before installation, turn off the device, safely depressurize the system, and clean the threaded hole. Then, confirm the compatibility of the plug's thread with the connection being secured.

The cap should be screwed in carefully, without excessive force. If clear resistance appears during installation, stop screwing and re-check the thread fit. Before starting the system, the plastic blanking plug must be removed and the final hydraulic connection must be made.

Various colors – random packing

M22x1,5 plastic blanking plugs are available in various colors. Color variants are packed and shipped randomly, so the color of the product received may differ from the one shown in the photo.

Color is not a basic parameter for technical selection. The most important thing is the compatibility of the M22x1,5 thread and the protective purpose of the plug.

Frequently Asked Questions (FAQ)

What thread does the M22x1,5 plastic blanking plug have?

The blanking plug has an external metric thread M22x1,5 with a nominal diameter of 22 mm and a pitch of 1,5 mm. It is intended for temporary protection of compatible holes with an internal thread.

Does the M22x1,5 plastic cap withstand hydraulic pressure?

No. The product does not withstand pressure loads and cannot be used to close an operating hydraulic system.

What is the M22x1,5 plastic blanking plug used for?

It is used for temporary protection of hoses, manifolds, cylinders, valves, and other components against contamination during transport, storage, repairs, and assembly.

Is the M22x1,5 thread the same as M22x1?

No. Both threads have the same nominal diameter of 22 mm, but they differ in pitch. M22x1,5 has a pitch of 1,5 mm, while M22x1 has a pitch of 1 mm. They should not be used interchangeably.

Can I choose the color of the plastic blanking plug?

The product is available in various colors, packed and shipped randomly. The color of the delivered plug may differ from the one shown in the photo.

Can a plastic blanking plug replace a steel hydraulic plug?

Not in a system operating under pressure. The plastic cap is only used for protection against contamination. To close operating connections, appropriately selected pressure plugs must be used.
