D38999/32Z21N

Glenair's D38999/32Z21N delivers mission-critical performance in Circular Connectors - Accessories for undersea exploration systems. This pressure-tolerant accessory maintains flawless operation at depths exceeding 6000 meters while ensuring signal integrity in harsh marine environments.Designed as Cap (Cover), Dust, this solution incorporates a patented pressure compensation system that equalizes to 9000psi external pressure. Testing confirms zero dielectric fluid leakage at crushing depths.Specifically engineered for MIL-DTL-38999 Series III Plug, the accessory meets API 17F subsea equipment standards. Its titanium construction resists pitting corrosion in high-salinity environments.Machined to 21 specifications with 0.002 tolerance, the component maintains perfect O-ring compression at all depths. The precision interface prevents hydrostatic lock during mating operations.The marine-grade Aluminum Alloy alloy demonstrates 99.9% corrosion resistance after 10-year simulated seawater exposure. The material's non-magnetic properties prevent interference with sensitive navigation instruments.Incorporating Contains Strap with Ring, Environment Resistant, this solution provides fiber optic and electrical power in a single hybrid interface. Its pressure-balanced oil-filled design ensures consistent performance regardless of ocean depth.The Black finish incorporates biofouling inhibitors that reduce marine growth by 70%. The coating maintains adhesion through 5000+ pressure cycles from surface to full ocean depth.
