Technical Advantages

We offer nut, sleeve, and union assemblies that suit tube OD from 1/8″ to 1″ (3 mm to 25 mm). These parts handle working pressures from 100 PSI to 1500 PSI and temperatures up to 400°F, depending on materials used. Our ferrules include single, double, and bite-type variants for better grip and long-term seal. With hex sizes up to 1.5″ and thread types from NPT to metric, installation aligns with standard tooling and no adapters are needed.

Industry Applications

Hydraulic Panels

Connects nylon and copper lines in control circuits, holding steady under mechanical stress

Refrigeration Systems

Seals refrigerant lines using brass or copper sleeves, reducing risk of long-term leakage.

Chemical Dispensing Units

Adapts to aggressive media with stainless sleeves and ENP-coated threads.

Automated Lubrication Systems

Handles oils and greases with grip-type ferrules that maintain seal under cycling pressure

Gas Burners

Links fuel supply lines with bite-type sleeves and BSP threads, built for temperature swings.

Water Filtration Units

Couples filter housings and tube lines, using NSF-compliant materials for potable water.

Adapting to Real System Demands

Every line design comes with space constraints, fluid behavior, or thread mismatches and our compression hardware adjusts to all of them. Whether you need a mix of BSP and metric threads, non-standard lengths, or ferrule material swaps, we offer full customization within your specs.
 
You avoid compromise and still meet performance, timeline, and pressure requirements without overpaying for generic builds. This balance of design control and material variety makes our brass hardware a smart fit across industries that rely on secure, adaptable joints. 

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can we ask for a mix of thread types and tube OD sizes within a single bulk order?

Yes, we can combine different thread standards and tube OD ranges in one production batch. This avoids placing multiple small orders and helps you match diverse connection needs in one shipment. We match each variant with the correct ferrule form and seal requirement.

Do you allow changes in ferrule design based on fluid type or tube material?

We offer single ferrule, double ferrule, and bite-type options depending on media pressure, tube hardness, and sealing requirements. You can specify sleeve form per line function. We also suggest alternatives if we see better grip or longevity based on your tubing. 

How do you manage part tolerances for high-vibration environments?

We maintain tight hex-to-body tolerance and controlled thread pitch, especially for unions in dynamic assemblies. For such use cases, we also provide anti-galling coatings and stainless sleeves. You can mention your stress test conditions, and we’ll align the build accordingly.

Can we define the length of compression union bodies instead of using fixed sizes?

Yes, we support non-standard overall lengths for union assemblies, depending on your routing or enclosure space. Length flexibility ranges from 0.5″ up to 4″, depending on the fitting type. We confirm thread engagement and wrench clearance before finalizing.

What is your MOQ and lead time if we need a mix of BSP, metric, and ENP-coated units?

We support mixed-type builds with a MOQ starting from 200 units per variant. Lead time ranges from 3 to 5 weeks based on coating and thread complexity. You can lock batch-wise dispatch if multiple coating processes are involved.
