Precision-engineered tube connector couplings and pipe to tube fitting connectors delivered to Iran
Haihao Group has recently completed the shipment of a batch of precision stainless steel connectors to a long-term industrial client in Iran. The products include tube connector couplings and pipe to tube fitting connectors, all manufactured from ASTM SS316 stainless steel and rated for Class 3000 service pressure.
SS316 Class 3000 Tube Connector Couplings Ferrule to Ferrule
Delivered Product Overview
The shipment consists of the following SS316 CL3000 fittings:
1. Tube Connector Coupling
- Port Type: Ferrule to Ferrule
- Material: ASTM SS316
- Size: 3/8″
- Pressure Rating: Class 3000
- Manufacturer Code: MFR
This tube connector coupling provides a secure and leak-tight connection between two tubes using a double ferrule compression design. Made from corrosion-resistant SS316 stainless steel, it is well-suited for instrumentation, chemical processing, and high-purity gas systems.
2. Pipe to Tube Fitting Connector
- Port Type: FNPT to Ferrule
- Material: ASTM SS316
- Sizes:
3/4″ FNPT × 3/8″ Tube
1/2″ FNPT × 3/8″ Tube - Pressure Rating: Class 3000
- Standard: MFR
These pipe to tube fitting connectors allow a seamless transition from threaded pipe (Female NPT) to tubing systems via ferrule compression. The compact body design ensures ease of installation even in confined spaces, while SS316 material guarantees superior resistance to chlorides and high-pressure media.
These pipe to tube fitting connectors and tube couplings are commonly used in instrumentation, fluid control, and high-pressure gas systems, where leak-tight performance and corrosion resistance are critical.

Why SS316 for High-Pressure Tube Fittings?
ASTM SS316 stainless steel offers superior corrosion resistance in aggressive environments, particularly those involving chlorides, acids, and saltwater. It also provides excellent mechanical strength and resistance to pitting, making it ideal for CL3000 pressure-rated tube fittings.
The ferrule design ensures a secure metal-to-metal seal under high-pressure conditions, maintaining connection integrity without additional sealing compounds.
Applications of SS316 CL3000 Tube Fittings
Our SS316 pipe to tube connectors are widely used across a variety of industries, including:
- Oil & Gas instrumentation lines
- Chemical processing plants
- Petrochemical distribution systems
- Hydraulic and pneumatic control panels
- Marine and offshore fluid systems
By combining FNPT to ferrule connections, these fittings provide a reliable interface between threaded pipe and compression tubing-critical in systems that demand safety, reliability, and zero leakage.
Manufacturing & Quality Control
All products were manufactured under Haihao Group’s ISO-certified quality system and inspected to ensure dimensional accuracy, thread integrity, and surface finish. The following tests and verifications were performed before shipment:
- Thread gauge inspection (NPT)
- Ferrule precision fitting check
- Visual and dimensional inspection
- Material traceability with full MTCs
Our CL3000 stainless steel fittings meet the highest industry standards, ready for direct integration into sensitive pressure systems.
