Phantom Stock Plan [Member]
Share-Based Compensation Arrangement by Share-Based Payment Award [Line Items]
Share based compensation, description				On April 1, 2006, the Company adopted the Omega Flex, Inc. 2006 Phantom Stock Plan (the “Plan”). The Plan authorizes the grant of up to one million units of phantom stock to employees, officers, or directors of the Company. The phantom stock units (“Units”) each represent a contractual right to payment of compensation in the future based on the market value of the Company’s common stock.
Share based compensation vesting rights				The Units are granted to participants upon the recommendation of the Company’s President, and the approval of the Compensation Committee. Each of the Units that are granted to a participant will be initially valued by the Compensation Committee at an amount equal to the closing price of the Company’s common stock on the grant date but are recorded at fair value using the Black-Sholes method as described below. The Units follow a vesting schedule, with a maximum vesting of three years after the grant date. Grants made on or after January 1, 2023, will fully vest three-years from the grant date. Upon vesting, the Units represent a contractual right of payment for the value of the Unit and therefore are stated as liabilities in accordance with FASB ASC Topic 718
