Female Connector – Instrumentation Tube Fittings (SS316/NPT/BSP)

BSC Engineering Solution offers precision-engineered female connectors designed for reliable and leak-free performance in critical instrumentation and process control systems. Our female connector fittings are widely used in industries such as oil & gas, petrochemical, chemical processing, and power generation, where secure and durable tube-to-thread connections are essential.

BSC Engineering’s Female Connector ensures reliable, leak‑tight tube‑to‑female‑thread connections for instrumentation and process lines. Available in SS316/SS316L (also Super Duplex on request), with NPT, BSPP, BSPT threads and tube sizes from 1/8″ to 1″ (3 mm to 25 mm). Clean‑room packed, pressure‑tested, and ready for rapid dispatch across India and internationally.

The Female Connector is a key component in tube fitting systems, joining a straight tube to a female threaded port. Engineered to deliver leak‑tight performance under vibration, thermal cycling, and corrosive media, our connectors help maintain system integrity and reduce maintenance downtime in oil & gas, petrochemical, power, water treatment, food & beverage, pharmaceuticals, and OEM machinery.

Note: Pressure and temperature ratings vary by size and alloy; refer to the technical chart below or request a datasheet.

Sizing & Selection

Select tube OD, thread type (NPT/BSPP/BSPT), and material to match service media and pressure. For chloride‑rich or offshore environments, choose Super Duplex. For sour service, request NACE compliant material.

Installation Notes

Ensure tube is cut square and deburred.
Insert tube to shoulder; tighten nut 1¼ turns past finger‑tight (new make‑up) or as per torque table.
Verify pull‑up with a mark or gap gauge.

FAQ

Q1. What is the difference between NPT, BSPP, and BSPT threads?
NPT is tapered per ASME B1.20.1; BSPP is parallel per ISO 228; BSPT is tapered per ISO 7. Match thread type to mating port to avoid leaks.

Q2. What pressure can the Female Connector handle?
Up to 6000 psi (414 bar) for common sizes in SS316 at ambient temperature. Check the datasheet for exact ratings.

Q3. Do you supply Super Duplex for offshore?
Yes. Super Duplex (S32750/S32760) is available with NACE MR0175 compliance.

Q4. Are these fittings interchangeable with other brands?
Our double‑ferrule design is compatible with industry standards, but we recommend using components from a single brand for critical service.

Q5. Can you provide test certificates?
Yes—MTC EN 10204 3.1, hydro‑test, and PMI can be provided on request.

Q6. Do you ship internationally?
Yes. Regular shipments to UAE, Saudi Arabia, USA, and UK with export documentation.
