Learning the Difference Between Fittings and Adapters

October 8, 2021

There are many crucial tools in the world of plumbing that serve unique and irreplaceable functions. Every network of pipes has essential pieces that can be replaced, upgraded and repaired to keep the water flowing at ideal rates. Two of these pieces, however, can be confused by amateurs or those who lack practical time with their tools. These are Fittings and Adapters. Though the terminology may be used interchangeably, the two pieces are very different and serve different functions in any given pipework.


What are Fittings?

Fittings are the joining parts that connect hard machine parts to tubes and other pipes. They must be fit onto one end securely and join with a larger component. The other end is then used to attach hoses, nozzles or pipes that otherwise couldn’t connect to the core component that they are leading into. These can also bridge between different standard measurements, allowing ORB ends to connect with JIC ends, as well as leading male-to-male connections if necessary. 


The function of a Fitting is to be easily replaceable or mobile from its core connection. It allows outer components to be more easily swapped out, if a new hose or pipe requires a different end to meet the core component, a fitting can bridge the gap immediately as long as it has the correct ends. 


What are Adapters?

Adapters are components which join two or more component ends, or threads, together. They are T-shaped, Cross-shaped or occasionally just simple two-ended components which allow for an easy transfer between multiple different component standards. 


Adapters are used for much more complex workings that need multiple connections going to and from a single component. Pumps that need to send fluid to multiple sources from a single output require adapters to make all of those connections. Adapters are also made specifically to bridge between different component standards, allowing exchange between SAE, JIC, ORB, Metric, NPT and other classifications. 


Why the Confusion?

The main confusion comes from the shared terminology of the two components. Adapters can function as fittings, in that they can only connect two pieces together, but not all adapters are fittings because many adapters are made to connect more than two things together, or have more than one component end type that need to lead into one another. There’s also the core function of bridging component standards that normally aren’t compatible. Fittings are normally used with like standards, serving as a bridge between two threads that aren’t compatible by nature. A fitting is needed for a hose to connect to a pump. An adapter is needed to connect the pump to more than one hose, where each hose may be of a different standard.


In some cases, the job of fittings and adapters can be interchangeable, and the choice of component comes down to availability. Fittings are the first tool you should consider for what goes into an open port, and adapters should be used in later stages of plumbing to make the whole system flow together.

The start of a new year is more than a calendar reset, it’s an opportunity to strengthen the systems that keep your business running efficiently. For industrial, commercial, and maintenance-driven operations, having the right supplies in place at the right time can mean the difference between staying productive or falling behind. Building a smarter supply strategy early in the year helps businesses control costs, reduce downtime, and remain competitive in an increasingly unpredictable supply environment. Here’s how to evaluate your needs, forecast usage, and put reliable systems in place for the year ahead. Why Strategic Supply Planning Matters Reactive purchasing often leads to higher costs, rushed decisions, and inconsistent inventory levels. Without a clear supply plan, businesses risk overordering, stockouts, and delays that impact operations and customer commitments. Strategic supply planning allows organizations to: Improve operational efficiency Reduce emergency purchases and downtime Stabilize pricing through better forecasting Build stronger supplier relationships When supply strategy is aligned with operational goals, purchasing becomes a competitive advantage, not just a necessity. Step 1: Evaluate Your Current Supply Usage The foundation of any effective supply strategy is understanding what you actually use. Reviewing historical purchasing data provides valuable insight into patterns, seasonality, and inefficiencies. Key questions to ask: Which products are used consistently throughout the year? Where do usage spikes or slowdowns occur? Which items frequently require rush orders or last-minute replenishment? Identifying high-use and critical items helps prioritize where planning and standardization will have the greatest impact. Step 2: Forecast Demand with Operational Input Accurate forecasting requires collaboration across departments. Operations, maintenance, and procurement teams all play a role in anticipating demand. Consider factors such as: Planned maintenance schedules Production volume expectations Seasonal workload fluctuations Equipment upgrades or expansions By incorporating operational insight into forecasting, businesses can better align inventory levels with real-world needs, reducing both excess stock and shortages. Step 3: Standardize Products and Vendors Standardization simplifies purchasing, improves consistency, and often reduces costs. Evaluating opportunities to standardize frequently used supplies—such as safety products, fasteners, tools, or consumables—can streamline procurement and inventory management. Working with a trusted supplier also provides access to product expertise, availability insights, and alternative solutions when supply challenges arise. Step 4: Set Systems in Place Early Establishing purchasing systems early in the year creates stability throughout the months ahead. This may include setting reorder points, implementing blanket orders, or coordinating scheduled deliveries for high-use items. Proactive systems reduce the need for emergency purchases and allow teams to focus on operations rather than constant supply management. Step 5: Build a Supply Partner, Not Just a Vendor A strong supply strategy goes beyond transactions. Partnering with a knowledgeable supplier adds value through product recommendations, inventory support, and responsiveness when challenges arise. The right supply partner understands your business, anticipates needs, and helps you adapt as conditions change throughout the year. How Action Supply Supports Smarter Supply Planning Action Supply works with businesses to develop supply strategies that support efficiency, reliability, and long-term success. By helping customers evaluate usage, identify opportunities for standardization, and implement dependable supply systems, Action Supply helps operations stay prepared, not reactive. Whether planning for routine maintenance, large-scale projects, or day-to-day operations, Action Supply provides the products and support businesses need to stay competitive all year. FAQs Why is supply planning important at the start of the year? Early planning helps businesses forecast demand, stabilize costs, and reduce disruptions caused by shortages or emergency purchases. How can businesses improve inventory efficiency? Evaluating usage data, forecasting demand, standardizing products, and working with a reliable supplier are key steps toward more efficient inventory management. What should a supply strategy include? A strong supply strategy includes usage evaluation, demand forecasting, product standardization, purchasing systems, and a trusted supply partner.
