1910.110(b)(9): LP-Gas Hose Specifications
LP-Gas hose must be made of materials resistant to LP-Gas, and hose under container pressure must be marked "LP-Gas" or "LPG" at not greater than 10-foot intervals and designed for a bursting pressure of not less than 1,250 p.s.i.g. Low-pressure side hose and connections have their own pressure ratings, and low-pressure hose for portable appliances used inside buildings must not exceed 6 feet except as provided and must not pass through walls, partitions, ceilings or floors.

Official text
(9) Hose specifications. 2 citations
(i) Hose shall be fabricated of materials that are resistant to the action of LP-Gas in the liquid and vapor phases. If wire braid is used for reinforcing the hose, it shall be of corrosion-resistant material such as stainless steel.
(ii) Hose subject to container pressure shall be marked “LP-Gas” or “LPG” at not greater than 10-foot intervals. 1 citations
(iii) Hose subject to container pressure shall be designed for a bursting pressure of not less than 1,250 p.s.i.g.
(iv) Hose subject to container pressure shall have its correctness as to design construction and performance determined by being listed (see § 1910.110(a)(15)).
(v) Hose connections subject to container pressure shall be capable of withstanding, without leakage, a test pressure of not less than 500 p.s.i.g.
(vi) Hose and hose connections on the low-pressure side of the regulator or reducing valve shall be designed for a bursting pressure of not less than 125 p.s.i.g. or five times the set pressure of the relief devices protecting that portion of the system, whichever is higher.
(vii) Hose may be used on the low-pressure side of regulators to connect to other than domestic and commercial gas appliances under the following conditions: Open (b)(9)(vii) 1 citations
(a) The appliances connected with hose shall be portable and need a flexible connection.
(b) For use inside buildings the hose shall be of minimum practical length, but shall not exceed 6 feet except as provided in paragraph (c)(5)(i)(g) of this section and shall not extend from one room to another, nor pass through any walls, partitions, ceilings, or floors. Such hose shall not be concealed from view or used in a concealed location. For use outside of buildings, the hose may exceed this length but shall be kept as short as practical.
(c) The hose shall be approved and shall not be used where it is likely to be subjected to temperatures above 125 °F. The hose shall be securely connected to the appliance and the use of rubber slip ends shall not be permitted.
(d) The shutoff valve for an appliance connected by hose shall be in the metal pipe or tubing and not at the appliance end of the hose. When shutoff valves are installed close to each other, precautions shall be taken to prevent operation of the wrong valve.
(e) Hose used for connecting to wall outlets shall be protected from physical damage.
