GL14/18 Open Top PBT Cap With Straight Plastic Hose Connection

1) Description

The red GL14 open-top screw cap with a straight PBT hose connection and natural silicone seal provides a secure and reliable connection between tubing and laboratory glassware.
Hoses can be securely connected to laboratory apparatus using plastic nozzles screwed onto a glass thread via a screw cap with a bore.

Plastic nozzles made of PBT offer excellent mechanical strength, temperature stability, and chemical resistance, while PP nozzles are suitable for applications with lower thermal or chemical resistance requirements.

The hose olive ensures a tight fit and prevents the hose from slipping off, making it ideal for fluid and gas transfer applications, filtration systems, or sampling setups.

2)Features

• Excellent chemical and thermal resistance.
• Standard GL14/18 thread fits most laboratory bottles.
• Straight hose connection for compact setups.
• Open-top design for flexible tubing access.
• Reusable and autoclavable construction.
• Red cap for easy identification.
