Engineering Overview: Precision Tube-to-Pipe Adapter Technology

Shrushti Metal is an ISO 9001:2015 certified manufacturer and stockist of high-integrity Instrumentation Tube Adapters in Kumbharwada, Mumbai. Engineered for critical chemical, hydraulic, gas, and instrumentation lines, our adapters provide leak-tight transitions between double ferrule tube fittings and threaded pipe ports.

Using tube adapters eliminates alignment stress and potential leak points. With a machined tube stub seated directly into a compression body, engineers can orient valves and gauges in any radial direction before tightening.

Frequently Asked Questions (FAQ)

Why use a tube adapter instead of a standard male connector?
Tube adapters eliminate alignment problems when connecting tubing to threaded ports. Because the tube stub rotates freely prior to tightening the compression nut, valves and gauges can be positioned perfectly without overtightening or damaging tapered threads.
Are Shrushti Metal tube adapters interchangeable with Swagelok and Parker?
Yes. Precision CNC tolerances guarantee 100% mechanical interchangeability and intermixability with Swagelok, Parker A-LOK, and other major instrumentation brands.
What test certificates are provided with every order?
Every shipment is accompanied by an authentic Manufacturer Test Certificate per EN 10204 Type 3.1, detailing chemical composition, tensile properties, and hydrostatic pressure testing.
How fast can Shrushti Metal dispatch orders across India?
Standard fractional and metric sizes in SS 316 and SS 304 are dispatched from our Mumbai warehouse within 24 hours of purchase order receipt.
