Graziano J. Gagliardi, 75, a retired custom cabinetmaker for the Freer Gallery of Art and owner of Gagliardi's Antique Shop in Washington for many years, died Sunday of cardiac arrest at Prince George's General Hospital.

Mr. Gagliardi was born in Torre Di Ruggero, Calabria, Italy, where he learned his craft.

He came to this country in 1923 and settled in this area. He went into the antique business and became well known in this area for his skills in antique restoration and reproduction. His clients included local furniture retailers, interior decorators and private collectors.

In 1957, he joined the Freer Gallery, where he specialized in custom-made display cases. He also reproduced bases for the gallery's oriental art objects, often working from photographs to obtain authenticity. He retired in 1976.

Mr. Gagliardi lived in Bethesda. Active in Roma Lodge No. 71 of the Sons of Italy, he had served as an officer and national deputy.

He also was a member of the Rock Creek Council of the Knights of Columbus and attended St. Jane de Chantel Catholic Church in Bethesda.

Survivors include his wife, Antoinette, of the home; a son, Joseph, of Bowie; a sister, Josephine Mossi of Chevy Chase, eight grandchildren and one great-grandson. Another son, Dr. Vincent Gagliardi, died in 1978.

The family suggests that expressions of sympathy be in the form of contributions to the Villa Rosa Nursing Home in Mitchellville, Md.
