FAQs
What are Dickie Dyer Pressure Test Nipples used for?
They are used for checking gas pressures in appliances and systems, and for setting gas governors. The design helps to control gas flow during connection and disconnection of testing equipment.
What material are these nipples made from?
They are made from corrosion-resistant polished brass.
Are these nipples suitable for all gas types?
They are manufactured to BS54161 standards for general use with gas appliances. Always confirm compatibility with your specific gas system and local regulations.
How does the small hole restrict gas flow?
The small hole is located within the nipple's passage. When the screw is removed to attach a gauge or tube, this hole limits the rate at which gas can escape, allowing for safer connections and more stable pressure readings.
What does 'Manufactured to BS54161' mean?
This indicates that the product has been manufactured in accordance with the specifications and safety requirements outlined in the British Standard BS54161, ensuring a level of quality and safety.
How many nipples are included in a pack?
Each pack contains three (3) pressure test nipples.
Can I use these for high-pressure industrial gas lines?
These nipples are designed for general use with appliances and systems. For high-pressure industrial applications, specialized equipment rated for those specific pressures and gas types should be used. Always consult the product specifications and your system requirements.
Troubleshooting
Nipple is difficult to screw in
Ensure the threads on the nipple and the port are clean and free from debris. Verify that the thread type and size are compatible. Do not force the fitting; check for cross-threading.
Leak detected around the nipple fitting
Turn off the gas supply immediately. Slightly tighten the nipple. If the leak persists, remove the nipple, inspect the threads for damage, and ensure a proper seal is possible. Consider using appropriate thread sealant tape if the fitting design allows and recommends it, though these are typically designed for a metal-to-metal seal.
Gas flow still seems high upon connection
Confirm that the correct nipple is being used and that the small internal hole is not obstructed. Ensure the screw mechanism is fully retracted.
