Industrial Fittings, Hydraulic, Instrumentation, Hose & Tube Fittings

Industrial fittings create the connections that hold fluid and gas systems together, and the integrity of every connection directly affects system reliability, safety, and maintenance cost. A leak at an instrumentation fitting can corrupt a pressure reading, expose technicians to process fluid, or trigger a safety shutdown. A failed hydraulic fitting can take a machine offline instantly. Proper fitting selection, matching connection style, material, pressure rating, and tube or hose type to the application, is not a detail to shortcut. At the same time, fittings are consumed in large quantities across any facility, making availability and fast delivery as important as product quality.

Shop Relevant stocks industrial fittings for hydraulic systems, instrumentation tubing, pneumatic lines, and fluid handling applications across manufacturing, chemical processing, oil & gas, and plant maintenance. The core of the catalog is Parker Instrumentation Products Division (IPD), more than 1,800 SKUs covering the full Parker A-Lok single-ferrule and CPI twin-ferrule compression tube fitting lines in stainless steel, brass, and carbon steel, along with Parker needle valves, ball valves, and manifold components. Beyond Parker, the catalog includes Dixon hose couplings, cam and groove couplings, and fluid transfer fittings; hydraulic fittings including standard and DIN bite-style configurations for high-pressure tube circuits; quick couplings in standard, high-flow, and connect-under-pressure styles for hydraulic service points and portable maintenance; barbed fittings for lower-pressure hose connections; clamp fittings for sanitary and process tube assemblies; PTFE hose fittings for chemical-resistant hose assemblies; and flanges for bolted pipe and hose connections requiring service access.

Applications include instrument hookups and sample lines, hydraulic power unit plumbing, compressed air distribution, chemical feed systems, analyzer panels, process piping tie-ins, and mobile equipment hydraulic maintenance. Shop Relevant ships most Parker IPD and Dixon fitting inventory the same day the order is placed. For specialty sizes, materials, or configurations, the Relevant Solutions team can assist with selection and sourcing.

Frequently Asked Questions

What types of fittings does Shop Relevant carry?

Shop Relevant stocks compression tube fittings (Parker A-Lok and CPI series), hydraulic fittings (DIN and standard), hose fittings, quick couplings (including high-flow and connect-under-pressure styles), clamp fittings, barbed fittings, flanges, and adapter accessories.

Do you carry Parker instrumentation fittings?

Yes. Parker Instrumentation Products Division (IPD) is our primary fitting line, with over 1,800 SKUs including A-Lok and CPI compression fittings, needle valves, ball valves, and tube fittings in stainless steel, brass, and other materials.

What's the difference between A-Lok and CPI fittings?

Both are Parker compression tube fittings. A-Lok uses a single-ferrule design, while CPI uses a two-ferrule design. Both create leak-free connections in instrumentation and process tubing. The Relevant Solutions team can help confirm which style suits your application.
