Hydraulic Application Plugs

 (3 product groups)

Hydraulic caps and plugs play a crucial role in protecting hydraulic systems from contaminants such as dirt, moisture, and corrosion. These components are especially important during manufacturing, transportation, storage, and handling - times when hydraulic ports and fittings are most exposed and at risk of damage. By preventing contamination, they help extend the life of the system and reduce the likelihood of costly failures.

Applications & Processes

Widely used across industrial environments, hydraulic plugs and caps are essential in:

  • Hydraulic hose assemblies
  • Metal fabrication and fluid transfer systems
  • Surface finishing processes like powder coating and painting
  • Machine assembly, servicing, and maintenance shutdowns

Material & Compatibility

Our hydraulic protection range is manufactured from high-quality materials such as:

Plastic: Lightweight and resistant to wear

LDPE: Ideal for temporary sealing with good chemical resistance

Flexible TPE: Offers excellent durability under mechanical and thermal stress

We provide solutions compatible with a wide variety of thread types including Metric, BSP, UNF, JIC, and non-threaded styles, ensuring a precise fit for your specific application.

Center Pull Tab Hose Plug

Center Pull Tab Hose Plugs are designed to plug and seal hose ends. They have ribs that ensure a tight fit when plugging hydraulic lines without straining them. It features a high tensile strength, toughness, and flexibility.

The internal, centrally located pull tab enables simple plug insertion and removal, making it a hassle-free alternative. Furthermore, the tapered form allows for the plugging of numerous interior diameters. The plugs snug fit and secure seal effectively prevents dust, dirt, and other impurities from entering the hose. This helps protect internal components, guaranteeing optimal performance.

Commonly used for construction, automotive, and agricultural applications.

  • Features a high tensile strength, toughness, and flexibility.
  • Features ribs that ensure a tight fit when plugging hydraulic lines without straining them.
  • The tapered form allows for the plugging of numerous interior diameters.

Hydraulic Quick Release Dust Plugs

These Hydraulic Quick Release Dust Plugs are meant to keep dust, debris, and other pollutants away from the male and female quick-release couplings. Designed to remain attached to the hose, establish a reliable seal, and prevent the introduction of unwanted particles, assuring the hydraulic system's best working and lifetime.

They may be used to plug ISO 7241-1 Series A and B Quick Couplings and have high corrosion and wear resistance. It can assist in increasing the life of hydraulic couplings by shielding them from pollution. This can result in cost savings on replacement. It also helps to improve the application's performance.

Features a user-friendly design that enables easy installation and removal using the pull tab on the side. It can resist temperatures of -40F to 275F (-40C to 135C). Suitable for various hydraulic applications, including construction equipment, agricultural machinery, industrial machinery, and oil and gas.
