Industrial spare fittings are an important component for the routing maintenance and out of the turn repairs. These fittings are designed as per the OEM requirements and engineered to deliver the reliable results. The construction material and designing can be dome to suit the typical application, if any.

A flareless fitting is an excellent fitting system for higher vibration hydraulic systems where a user does not wish to use flare tubing. Due to this various pipe fittings, tube fittings, connectors etc are flareless biting type and hence the spare fittings are no exception.

In dynamic hydraulic systems, the flareless tube fitting is recommended over other flareless tube fitting systems, specifically for compression, or "instrumentation." The design of the flareless single biting ferrule holds the key to this superiority. The ferrule bows during assembly and "bites" into the tubing wall. The spring-action joint provides superior shock absorption and holding power. In addition, the bite and other visual cues, allow a user to inspect the assembly prior to system pressurization. With other flareless tube fitting systems, a user must rely on indirect verification of a positive seal through the use of gap gauges or by counting the number of hex flats torqued from a finger-tight position.

The finish of the flareless fittings can be dark graphite color due to lubricant coating and in some cases the fitting nut has a bonded dry film lubricant which aids in the installation process to reduce torque and prevent galling.

Some of the frequently used flareless biting type spare fittings are:
