Main Block Series

Product catalog summary
Main Block Series
Designed for assembling manifold blocks for concentrated branching, the Main Block Series is compatible with 14 different size blocks. It offers the same flow rate as steel piping but with a body half the size.
Fitting Series
This series includes various types such as Twist-Proof, Rotary, Stop Fitting, and Minimal Series, with specialized applications like Die Temperature Control and Anti-spatter.
Specifications
The fluid medium is air, with a maximum operating pressure of 1.0MPa and a maximum vacuum of -100kPa. The operating temperature range is 0~60℃, with no freezing allowed.
Construction (MHQ)
Components include an elastic sleeve, female thread, tube, release ring, lock-claws, O-ring, and fitting body. Materials used are NBR, POM, stainless steel, PBT, and nickel-plated brass.
Model Designation
Model codes specify joint connecting thread size and air port size. Resin color options are Standard (Black) or Light-gray.
Safety Instructions
Brackets should be used when connecting multiple blocks to prevent damage. Main block spanners are recommended for assembly to avoid deformation. Tightening torque varies by thread size.
Assembly Instructions
Main blocks can be connected if metric thread sizes match. Various types of ports and plugs are available for customization, and fixing brackets are necessary for certain configurations.
How to Insert and Disconnect
Tubes are inserted into Push-In Fittings and locked automatically. Disconnection requires stopping air supply and pushing the release ring. Thread tightening should be done with a spanner.
CAD Data
CAD files are available for various components like Bush A, Elbow, Bulkhead Reducer, and more.
Specifications and Model Information
The document provides detailed specifications for various PISCO products, including model codes, dimensions, and weights. CAD data for these products is available on the PISCO website.
Safety Instructions
Safety instructions are categorized into 'Danger', 'Warning', and 'Caution' to prevent personal injury and property damage. Key points include selecting pneumatic products by experienced designers, proper handling and maintenance, and ensuring safety measures before operation. Specific warnings include avoiding use in life-supporting equipment, exposure to corrosive environments, and improper disassembly.
Disclaimer
PISCO disclaims responsibility for indirect losses, improper use, or modifications of their products. Liability is limited to the cost of the product.
Installation and Maintenance Guidelines
Instructions for proper installation and maintenance of fittings and tubes include ensuring correct tube insertion and disconnection, using appropriate tools and torque for fitting installation, and avoiding excessive loads on fittings and tubes. Recommended torque values and material specifications are detailed in tables.
Common Safety Instructions for Fittings
General guidelines for using PISCO fittings include using fittings only with air or water unless specified otherwise, avoiding use in environments with flames or weld spatter unless using specific series, and ensuring proper tube diameter tolerance when using non-PISCO tubes.
Tube End Sealing
Ensure the tube is fully inserted to prevent disconnection. After insertion, verify proper placement by pulling moderately.
Instructions for Tube Disconnection
Before disconnecting, ensure no air pressure is inside the tube. Push the release-ring of the push-in fitting evenly and deeply to pull out the tube. Insufficient pushing may cause damage or leave shavings inside, leading to leakage.
Instructions for Removing a Fitting
Use appropriate tools to loosen a hexagonal-column or inner hexagonal socket. Remove any sealant from the mating equipment to prevent malfunctions.
Instructions for Installing a Fitting
Use proper tools to tighten a hexagonal-column or inner hexagonal socket. Avoid contact with lock-claws to prevent system performance issues. Refer to recommended tightening torque limits to avoid thread or gasket damage, which can cause fluid leakage. Adjust tube direction within these limits during installation.
Piping Arrangement
Avoid loads on fittings and tubes such as twists, tensile, moment load, shaking, and physical impact to prevent damage, deformation, or tube escape.
Recommended Tightening Torque
The document provides a table with recommended tightening torque values for various thread types and sizes, along with sealock colors and gasket materials. These values may vary for some products, so refer to specific specifications as needed.
