Product overview
Complete Assembly Configuration & Sealing Principle
This complete IDF hygienic pipe union assembly brings together four matched subcomponents: an IDF-13H hexagonal retaining nut, an IDF-14 butt-weld liner, an IDF-15 butt-weld male end with external ACME threads, and a T-section IDF-14G union gasket. Wrench-tightening the six-flat hex nut draws the liner and male end together around the gasket to create a flush, crevice-controlled bore for dairy and beverage lines.
Material Grades & Subcomponent Dimensional Schedules
Available in SS304 and SS316L stainless steel across six nominal sizes from 1.0" through 4.0" (1.0", 1.5", 2.0", 2.5", 3.0", and 4.0"), the assembly matches inch-OD tubing from 25.4 mm to 101.6 mm (bore ID 22.2 mm to 97.6 mm). The composite source drawing sheets provide full subcomponent schedules for the IDF-13H hex nut (SW 46 mm to 133 mm), IDF-14 liner, IDF-15 male end, and IDF-14G gasket (height 7 mm), alongside reference dimensions for the alternative IDF-13R slotted round nut.
Specification & Ordering Notes
Because the series specification does not restrict the IDF-14G gasket to a single elastomer compound, specify your required seal material, stainless steel grade for wetted ends and hex nut, and nominal tube size when placing an order.
