Compression fittings can be dubbed as the “space eliminators”, effectively removing gaps between joints to ensure a watertight seal.

Play plumber for the day once you get to speed on compression tube fittings, which are a handyman’s or handywoman’s staple pipe or valve coupling component.

The anatomy of a hydraulic compression tube fitting includes the compression nut, the ring and the seat; all three vital parts of this type of coupling joins two pipes or tubes together using compressed force.

From household water faucet leaks to industrial draining system applications, compression fittings can be dubbed as the “space eliminators”, effectively removing gaps between joints to ensure a watertight seal.

Now, get the seal of approval of fitting material basics: in addition to proper sizing, correct material selection of fittings is key to accurate application performance. Carbon steel and stainless steel are commonly chosen materials used to fit quite fittingly in tight tolerances.

Carbon steel fittings go well with welding

Remember the brief anatomy tutorial that compression fittings are made in three parts? First up is compression nuts, which are cold formed to enhance its grain structure and overall strength.

Next, the cutting ring is comprised of hardened steel and cadmium plated. Finally, the main compression body are made either from bar stock (for straight connectors and couplings) or forged blanks (typically used in shaped fittings).

Carbon steel fittings have a surface finish of plated zinc or nickel zinc; for those welding applications, a finish of oil is applied to the fitting body to boost its welding efficacy.

Stainless steel fittings do well with adapting

Dimensionally identical to carbon steel fittings, stainless steel fittings are constructed are 100% interchangeable.

Engineered with stainless steel ferrules bearing precise hardness to safeguard hardness and durable sealing properties, these specific fittings go hand in hand with steel tubing.

The versatility of stainless steel allows systems requiring steel fittings in some locations while stainless steel in others provides flexibility with designing different fitting styles while using the same material.

Manufactured in light, medium and heavy duty series construction, fittings can provide a perfect fit with maximum psi rates from 1500 psi to 11,600 psi.
