Female Connectors
What are Female Connectors?
Female Connectors are precision fittings used to connect instrument tubing to components or valves via an internal (female) thread. They form a secure, leak-proof seal in high-pressure instrumentation systems and are essential in chemical plants, oil & gas installations, and analytical laboratories.
Asiad Steel Industries is a leading supplier of high-quality Female Connectors, trusted by industries for reliability and precision. Our fittings are engineered to meet demanding performance and dimensional standards, ensuring safe and efficient system operation.
Key Features
- Internal Thread Interface – Accepts male-threaded fittings for compact connection.
- Reliable Pressure Seal – Maintains seal integrity under vibration and temperature swings.
- Wide Thread Standards – Available in NPT, BSP, ISO, and custom thread options.
- Corrosion-Resistant Materials – Ideal for chemical, saline, and offshore use.
- High Accuracy Machining – Ensures alignment and repeatability in instrumentation lines.

Do you have questions?
Can female connectors be used with compression tube fittings?
Yes, many female connectors come with dual options—threaded and compression ends.
What materials are suitable for acidic or corrosive media?
SS 316, Hastelloy, and Alloy 20 are recommended for aggressive environments.
Do female connectors require sealing tape?
Yes, use PTFE tape or compatible sealant to ensure tight joints under pressure.
Do you supply bulk or small-batch quantities?
Yes. We cater to both small-scale lab setups and bulk industrial procurement.
