G30 series are high pressure application connectors, which are the optimal outer diameter connection solution for sealing all kinds of copper, steel and aluminum tubes, extensively applied in refrigeration and new energy industries, such as heat exchangers, pressure vessels,instruments,meters, motor controller cooling plates, etc.

High pressure externally connection solutions

---

• Reducing overall manufacturing costs through more efficient testing
• Eliminating waste arising from failed tests
• Improving the stability of the entire testing process
• Metal locking structure to enhance the upper limit of test pressure

Features of G30 Series Connectors

• 1. Pressure-assisted safety Design

  The sealing force is strengthened with the increase of test pressure

• 2. Level actuated operation

  The test tube is inserted into the sealing hole at the front of the connector, folding the handle by 90° to achieve a sealed connection

• 3. High Hardness Locking collets

  The surface of the collet is covered with engraved lines to increase the force area and provide higher gripping force, high hardness dowels are available to clamp stainless steel and mild steel

• 4. BSPT Thread Termination port

  Standard BSPT1/8 or 1/4 threaded hole on the side, more suitable for international application scenarios

• 5.Easy disconnection

  Once the test air pressure is completely removed, the handle will be folded back to the original position and the sealing effect will disappear to achieve safe disconnection

Display
G30 Series connectors included 7 types of British models, 8 types of metric models, satisfying the sealing range of 6 mm -22.23 mm

Features and advantages of G30 Series Connectors

High Hardness Locking collets: Featuring locking collets that firmly clamp the outer wall of the tubing and increase the upper limit of test pressure

Horizontal Pattern Feature: Locking jaws are covered with tiny stripes engraved line to increase the force area and provide a firmer grip.

Automatic Repositioning: Allowing effortless operation, reducing the risk of jamming and raising operational efficiency

Nylon Handle: Ergonomic design, more comfortable for operation

BSPT terminationport:In line with international standards, commonly adopted, related accessories are easily available
