Description

Plastic threaded plug / cap male thread M20x1.5

The M20x1.5 screw-in plastic plug is a protective cap with a metric male thread, designed for the temporary closing of holes and connections with an M20x1.5 female thread. The product protects hydraulic system components from dust, dirt, shavings, and other contaminants that may enter the system during transport, storage, repairs, and assembly.

The cap is made of plastic and is used for the protective sealing of hoses, distributor inlets and outlets, actuators, and other hydraulic components. The M20x1.5 male thread allows the plug to be screwed into a compatible hole, helping to keep the connection clean until the hose or other system component is reconnected.

Important: the M20x1.5 plastic plug does not withstand pressure loads. It is not intended for closing hydraulic systems while operating under pressure.

Color information: the product comes in various colors, which are packed and shipped randomly. The color of the received plug may differ from the one shown in the photo.

Application: protection of hoses, distributors, actuators, and other components.

Use of the M20x1.5 protective cap in power hydraulics

The GZ M20x1.5 plastic plug is designed for temporary protection of hydraulic connections during assembly, maintenance, and repair work. It helps protect threaded holes from contaminants and reduces the risk of small particles entering the components.

The plug can be used in compatible holes of hydraulic hoses and fittings, distributor inlets and outlets, actuator connections, and other elements with an internal M20x1.5 thread. It also works well during the transport and storage of parts that have not yet been installed in the device.

M20x1.5 male thread – dimensions and identification

The designation M20x1.5 refers to a metric thread with a nominal diameter of 20 mm and a pitch of 1.5 mm. It is a fine thread, used, among others, in the connections of hydraulic components.

When selecting a plug, check the diameter and thread pitch of the hole to be protected. You can use a caliper and a metric thread pitch gauge. Compatibility of the nominal diameter alone is not enough, as M20 threads with different pitches are not interchangeable.

Protection of connections against dust, dirt, and contaminants

During the repair of hydraulic machinery and equipment, disconnected hoses and open connections are exposed to dust, sand, metal shavings, and other contaminants. Using an M20x1.5 plastic plug allows for temporary closing of a compatible hole, limiting the access of contaminants to its interior.

Protecting the cleanliness of components is important during repairs of power hydraulic systems, where contamination can negatively affect the operation of valves, distributors, and other precision elements.

M20x1.5 plastic plug for transport and storage

The protective cap can be used during the transport of hydraulic parts and the storage of components in a warehouse or workshop. Temporary closure of the hole helps limit contact of the connection's interior with dust, dirt, and accidental foreign objects.

The plug is also useful when preparing devices for assembly. Before starting the system, remove the protective cap and make the final hydraulic connection.

Plastic – lightweight protective cap

The GZ M20x1.5 plug is made of plastic. Its function is to protect the thread and connection hole during activities where the component is not subjected to pressure loads.

The plastic construction is not intended to replace steel hydraulic plugs operating under pressure. During assembly, avoid excessive force, which could lead to damage to the thread or the plug body.

Protective cap vs. pressure hydraulic plug

The M20x1.5 plastic plug is a protective element used for temporary protection of threads and connections. It does not withstand pressure loads and cannot replace a working plug intended for closing the system during its normal operation.

If a hole is to remain closed in a system under pressure, an appropriately selected hydraulic plug with confirmed strength parameters and the correct sealing method must be used. A matching M20x1.5 thread does not mean that both types of plugs are interchangeable.

How to choose a plastic male thread M20x1.5 plug?

Before purchasing, ensure that the hole to be protected has an M20x1.5 internal metric thread. It is important to confirm the nominal diameter of 20 mm, the pitch of 1.5 mm, and the appropriate hole depth.

The purpose of the protection should also be defined. The product is suitable for temporary protection of connections during transport, storage, and repairs, but not for operation under pressure.

Installation and removal of the M20x1.5 plastic plug

Before installation, make sure the system is turned off and depressurized. Then check the cleanliness and condition of the internal thread to avoid damaging the plastic plug.

The plug should be screwed in carefully, without using excessive force. If significant resistance occurs during installation, check the thread compatibility. Before starting the hydraulic system, the plug must be removed and replaced with the final connection or a pressure plug selected for the given connection.

Available colors and packaging method

M20x1.5 male thread plastic plugs are available in various colors. Individual color variants are packed randomly, so the delivered product may have a different color than the item shown in the photo.

Color is not a criterion for the technical selection of the plug. When purchasing, focus primarily on the M20x1.5 thread size, its compatibility with the hole to be protected, and the protective purpose of the product.

Frequently Asked Questions (FAQ)

What thread does the M20x1.5 plastic plug have?

The plug has a metric male thread M20x1.5 with a nominal diameter of 20 mm and a pitch of 1.5 mm.

Does the M20x1.5 plastic plug withstand hydraulic pressure?

No. The plug is protective in nature and does not withstand pressure loads. It must not be used as a plug for closing an operating hydraulic system.

What is the plastic male thread M20x1.5 plug used for?

It is used for the temporary protection of hoses, distributor connections, actuators, and other components from dirt during transport, storage, assembly, and repair.

Can I choose the color of the plug?

The product comes in various colors, which are packed and shipped randomly. The color of the received plug may differ from the one shown in the photo.

Can the M20x1.5 plug replace a steel hydraulic plug?

Not in a system operating under pressure. The plastic plug is for protecting connections, while a pressure plug must have a suitable design and confirmed operating parameters.
