1 I — – – – – –
Connector for manufactured (mobile) homes — a connector for use between the permanent gas outlet of a manufactured (mobile) home park lot and the piping inlet on a manufactured (mobile) home.
Crossover connector — a connector for use between the sections of a multiple section manufactured (mobile) home.
Connector nut — a threaded nut permanently attached to a connector conduit which mates with an adapter or manual valve to form a union joint.
Gas hose connector — a connector designed for use only with portable gas-burning equipment. The gas conduit depends for gastightness on the wall structure of the hose material. The conduit may be supported with internal metal or other reinforcement. The design and application presuppose that the connector will not be pressurized when the appliance served by the connector is not in use. Gas hose connector includes:
Gas hose connector for portable outdoor gas-fired appliance — a gas hose connector for use with portable gas-burning equipment used outdoors.
Gas valve — a manually operated valve that permits control of the flow of gas at any rate from none to “full on.”
Listed — equipment or materials included in a list published by a nationally recognized testing laboratory, inspection agency, or other organization concerned with product evaluation that maintains periodic inspection of production of listed equipment or materials and whose listing states either that the equipment or material meets nationally recognized standards or has been tested and found suitable for use in a specified manner.
Propane — a liquefied petroleum gas that is classified as either “commercial propane” or “Special-Duty” propane in accordance with ASTM D1835, Standard Specification for Liquefied Petroleum (LP) Gases. Special-Duty propane is equivalent to Propane HD-5.
Propane HD-5 — propane that complies with the same requirements as “Special-Duty” propane, as defined in ASTM D1835, Standard Specification for Liquefied Petroleum (LP) Gases.
Protective coating — as used in this Standard, material applied to the exterior surface of the connector to enhance resistance to corrosive materials.
Tubing — as used in this Standard, the material from which the gas conduit of a connector is fabricated.
Union — an assembly of parts to facilitate connection or disconnection between the connector and gas piping without rotation of the connector tubing.
Union, ground joint — a union consisting of three parts (nut, swivel, and end piece) concentrically machined to provide alignment.
5.3.2
A connector shall withstand, without evidence of leakage or becoming detached, a lengthwise pull of
800 lb/in (3.56 kN) of nominal connector l.D.
Method of Test
A new, unused connector shall be used for this test.
One end of a 2 ft (610 mm) connector shall be securely attached to a stationary pipe to which an air supply system and pressure gauge is connected. The other end shall be securely attached in a similar manner to a closed pipe connected to a mechanical means by which a constant pulling force of the necessary magnitude can be applied.
The required tension shall be applied to the connector and maintained for the duration of the test. At the end of 5 minutes, the connector shall be subjected to 3 psi (20.7 kPa) air pressure. The air shall then be shut off, and there shall be no leakage as evidenced by the pressure gauge during a period of 1 minute thereafter (see Clause 5.1.3-b).
5.3.3
A connector shall be sufficiently resistant to crushing to support a transverse load of 75 lb per linear in
(1.35 kg/mm) without loss of capacity beyond that specified in the following Method of Test and
without developing leakage.
Method of Test
This test shall be conducted after the capacity of a 6 ft (1.83 m) connector has been determined as specified in Clause 5.9, Capacity.CSA ANSI Z21.75  pdf download.
