Brass BSPT Compression Glands: 1/8" to 1/2" Thread, 3-6mm Diameter

The Reliable Seal for Your Temperature Probes and Sensors

In industrial and commercial applications, achieving a secure and leak-proof seal for your probes is critical for both safety and measurement accuracy. A loose or improper fitting can lead to liquid or gas leaks and compromise the integrity of your process.

Our Brass BSPT Compression Glands provide a robust and dependable solution for mounting probes and sensors in tanks and vessels. Designed to accommodate diameters from 3mm to 6mm, this range of glands is compatible with a wide array of thermocouple probes. The external BSPT (British Standard Pipe Taper) thread comes in sizes from 1/8" to 1/2", allowing for a perfect fit into female threaded fittings. The precision-engineered internal olive compresses tightly around your probe as you screw the gland into place, creating a powerful, leak-proof seal that holds firm under pressure. This durable brass fitting is the professional's choice for a clean, secure, and long-lasting installation.

Key Features & Benefits

• Broad Compatibility: Fits probes and sensors with diameters ranging from 3mm to 6mm, making it a versatile choice for many applications.
• Wide Thread Size Range: Available with external BSPT threads from 1/8" to 1/2", ensuring you can find a perfect fit for your existing equipment.
• Durable Brass Construction: Machined from high-quality brass, these glands provide excellent corrosion resistance and a long service life in demanding environments.
• Leak-Proof Compression Seal: The internal olive creates a powerful mechanical seal, securely gripping the probe and preventing leaks of liquids or gases.
• Flush & Secure Mounting: Ideal for mounting probes to tanks, vessels, and pipes, providing a professional and stable fitting.
• Reusable Design: The glands can be disassembled and re-used, making them a cost-effective solution for maintenance and sensor replacement.

How It Works: Simple & Secure Installation

Installing a probe with our compression gland is a straightforward two-step process:

1. Preparation: Simply slide the compression gland's body and internal olive onto your probe or thermocouple.
2. Compression: Screw the external BSPT thread into a female threaded fitting on your tank or vessel. As you tighten, the internal olive compresses around the probe, creating a powerful, mechanical seal that holds the probe firmly in place.

This process ensures a strong, reliable, and leak-tight connection every time.

Frequently Asked Questions (FAQs)

Q1: What is the difference between BSPT and BSPP threads?

A1: BSPT (Tapered) threads are designed to create a seal by wedging the threads together. BSPP (Parallel) threads require a separate gasket or washer to create a seal. The taper on BSPT threads makes a more reliable seal for high-pressure or critical applications.

Q2: How do I know which size to order?

A2: You need to measure two things:

1. The outer diameter of your probe or sensor (to choose the correct internal diameter: 3mm, 4mm, etc.).

2. The thread size of the female fitting on your tank or vessel (to choose the correct external BSPT thread: 1/8", 1/4", etc.).

Q3: Can these glands be used more than once?

A3: Yes, the glands are designed to be reusable. However, the internal olive creates a strong crimp. If you're removing and re-installing the same probe, it will likely work fine. If you're fitting a new probe, it's often best to use a new olive to ensure the best possible seal.
