Reduce Leaks and Improve Operations

Meeting your highest expectations for safety and dependability

The Swagelok Tube Fitting Advantage

The Swagelok Tube Fitting Advantage

Proven design, manufacturing excellence, and superior raw materials combine to ensure that every Swagelok fitting meets our customers’ highest expectations. When properly installed, Swagelok’s two-ferrule, compression-grip tube fittings produce a repeatable, leak-tight seal, even after being reassembled multiple times.

The Lowdown on Leakage

Choosing the most reliable fittings and installing them correctly can save you money and make the workplace safer. Consider the many costs and consequences of leakage:

leaks contribute to wasted fluid

Lost Fluid

Millions of gallons are wasted each year (1 gallon of hydraulic fluid = ~$14 USD)

leaks contribute to lost production in offshore oil

Lost Production

Especially important in offshore oil where laws already limit production to a specific number of days per month

leaks contribute to equipment damage

Equipment Damage

Loss of lubrication can lead to premature wear/machine failure

leaks contribute to off-specification product

Off-Specification Product

Can be produced inadvertently due to improperly calibrated or operating instruments; material must be reworked, sold at reduced price, or disposed of

leaks contributed to a degraded work environment

Degraded Work Environment

Oil drippage can cause accidents; emissions can be expensive, dangerous — even illegal

leaks can lead to noncompliance fines

Fines for Noncompliance

Systems and equipment that violate validated processes can quickly become costly

leaks contribute to mass cleanup efforts


It takes time to locate and repair leaks; some call for special teams to manage toxic chemicals. There’s also the cost of shutting down a system to thoroughly clean it

1. Better by Design

We outperform other fittings in three key areas — tube grip, gas seal, and vibration resistance.

Repeatable, leak-tight connections

Swagelok tube fittings have a grip-type design that uses a unique “hinging and colleting” action to achieve optimal performance in three key areas.

  • Tube grip: hinging and colleting action provides more direct tube contact/gripping support.
  • Gas seal: burnishing and polishing action of the front ferrule creates concentrated zones of contact on the tube and on the body bevel for a stronger seal.
  • Vibration resistance: the colleting region better isolates stress risers at the tube grip to resist bending, deflection, and vibration.

SAT12® Carburization Process

Swagelok’s unique low-temperature carburization process provides tool-steel-like hardness and strength in the rear ferrule without sacrificing corrosion resistance or material ductility.

Easy to Install

Quick assembly and reassembly using only standard wrenches make our fittings easy to install. Our expert training equips your workforce with essential skills for installing fittings across all your applications.

Rigorous Testing

swagelok product testing

Swagelok fittings are subjected to extreme burn, rotary flex, impulse, corrosion, and shock impact testing. Some tests take as many as 10 million cycles to complete.

Thousands of samples of production tube fittings are tested in our state-of-the-art labs to ensure only highly reliable components.

We offer the most comprehensive tube fitting Product Test Reports (PTRs) in the industry.

2. A Material Difference

swagelok fittings composition

In all stainless steels, chromium and nickel are critical for corrosion resistance and ductility. Because our 316 SS tube fittings contain more chromium and nickel than industry standards require, you can make the most of resources while achieving optimal performance by combining our 316 SS fittings with compatible alloy tubing in Engineered Combinations.

3. Low Cost of Ownership

low cost of ownership for swagelok fittings

The price of a fitting is only part of its actual cost. Swagelok two-ferrule, compression-grip fittings cost less to own over the life of the fitting. Better design and reliability mean less investment in replacement and more investment in your operation.

  • Leak-tight design = less risk of costly accidents and media loss
  • Optimal reliability = lower maintenance costs and minimal downtime

4. Services Tailored to You
