Integral Union Connections for Oil and Gas

Precision-Machined Flow Iron Components Built to U.S. Oilfield Standards


Integral Fitting Union Connection - Align MFG components
Overview

Integral Union Connections Manufacturing

In high-pressure oil and gas operations, every connection counts. Integral union components, forged or machined fittings with built-in hammer union ends, are the backbone of flexible, modular flow systems used in fracturing, well testing, flowback, and production.

At Align Manufacturing, we supply OEMs and pressure equipment builders with high-precision integral union parts, produced offshore under strict quality oversight. From elbows and tees to crosses and straight pup joints, we deliver machined components designed to withstand extreme pressures, cyclic loading, and abrasive flow.

Key Features

Integral Union Connections in Manifolds and Flow Systems

Integral union fittings are essential building blocks in larger oilfield systems. They serve as key connection points in manifold skids, frac iron strings, and flowback packages where fast, reliable sealing is non-negotiable.

By manufacturing these critical components to API 6A and NACE MR0175 standards — and by managing every step of the offshore process — Align ensures your systems perform predictably, job after job.
