For hoses and piping, a quick connect fitting, also called a push fitting or Quick Connect Coupling, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves ...
John Guest (Established in 1961, West Drayton, UK) developed the Speedfit push-fit connector for compressed air use in 1974, and introduced plumbing fittings in 1987. [2] These fittings are white plastic, and are unscrewable to replace components, like Hep2O, but also have a push-release mechanism. Speedfit uses plastic pipe support inserts.
Piping or tubing is usually inserted into fittings to make connections. Connectors are assigned a gender, abbreviated M or F. An example of this is a "3 ⁄ 4-inch female adapter NPT", which would have a corresponding male connection of the same size and thread standard (in this case also NPT).
The solenoid/diaphragm timer uses more battery power throughout the "on" cycle because the solenoid must be actuated the entire time that the water flow is "on". The ball valve timer using the motor and gear actuator only uses more battery power during the few seconds that motor is used to turn the water flow on or off.
The male and female straight (non-tapered) threads screw together and the connection is sealed with a gasket. The type of threaded coupling with a pin-lug swivel used on fire hoses was first manufactured prior to 1873 in the U.S.: Unknown patent by Charles W. Emery, dated July 11, 1865, 1874: Hose-couplings, No. 149,029 by W. A. Caswell
The hose is then fit onto the barb, the clamp expanded again, slid onto the portion of the hose over the barb, then released, compressing the hose onto the barb. Clamps of this design are rarely used for high pressures or large hoses, as they would require unwieldy amounts of steel to generate enough clamping force, and be impossible to work ...
