Core Features and Applications

Solves the compatibility issues between interfaces of different national/regional standards (e.g., US NPT, European ISO, Japanese JIS) or different brand equipment.
Suitable for various industrial scenarios such as petrochemical, semiconductor manufacturing, medical devices, laboratory instruments, and more.

Cross-Standard Connection

System Integration

Tube fitting adaptor Used with regulators, flow meters, pumps, valves, and other components to ensure the sealing and reliability of high-pressure/vacuum systems.
Supports modular design and quick maintenance of complex pipeline systems.

Diverse Interface Types

NPT: US standard tapered thread, suitable for medium and low-pressure sealing, relies on thread engagement for sealing.

TUBE FITTING: Ferrule-style connection, seals by tightening metal tubes, easy to install and remove.

TUBE WELD: Welded interface, provides permanent, high-seal connections, suitable for high-temperature/high-pressure environments.

VCR: Metal face seals (e.g., nickel alloy gaskets), specifically used for ultra-high vacuum or clean systems (such as semiconductor industries).

Frequently Asked Questions (FAQ)

1. How to select an tube fitting adaptor model?

Specify the standard of the original and target interfaces (e.g., NPT 1/4" to VCR 1/2"), pressure rating, and medium type (gas/liquid/corrosive fluids).

2. What's the difference between NPT and BSPT threads?

NPT has a 60-degree tapered thread (US standard), while BSPT has a 55-degree tapered thread (British standard). The two are not compatible and require an adapter.

3. Is sealing tape or thread sealant required during installation?

NPT threads typically require a sealant; however, metal-sealed interfaces like VCR should not use sealants and rely on gaskets for sealing.

4. What is the maximum working pressure/temperature of the adapter?

Depending on the material and type, stainless steel adapters commonly withstand pressures up to 10,000 psi, with temperature ranges from -200°C to 400°C (specific model parameters apply).

5. Can special angle or multi-function adapters be customized?

Custom designs for L-shaped, T-shaped, Y-shaped multi-channel configurations, or integrated pressure gauge interfaces are available.

6. How to prevent leakage issues?

NPT threads typically require a sealant; however, metal-sealed interfaces like VCR should not use sealants and rely on gaskets for sealing.

7. Applicable Customer Groups

Equipment manufacturers (requiring adaptation to multi-country export models)
