Premium British Standard Parallel Pipe (BSPP) Fluid Connectors
Fitsch is a premier China hydraulic adapter manufacturer and factory, specialized in engineering high-pressure BSPP Stainless Steel Hydraulic Adapters strictly built to BS 5200 and ISO 8434-6 international standards. Utilizing the time-tested 60° cone sealing profile, these parallel British thread fittings are universally adopted across European, British, and international fluid power networks.
By sourcing high-grade 304 and 316 stainless steel, Fitsch prevents structural oxidation, scaling, and thread galling in demanding operational conditions. The metal-to-metal 60-degree cone profile offers exceptional sealing reliability under intensive hydraulic pulsation and mechanical vibration, ensuring safe containment in marine, offshore oil and gas, material handling, and process industries.
Comprehensive Product Configurations & Core Types
We manufacture and stock a deep inventory of standard BSPP adapters in Straight, Forged 90° Elbow, 45° Elbow, and Tee geometries, explicitly configured into the following core product lines:
1. Straight Unions
Engineered to connect two male or female BSPP hose lines or rigid tubes in a straight line. Our BSPP Straight Unions maintain a smooth internal diameter to minimize pressure drops and optimize laminar fluid flow.
2. Bulkhead Unions
Designed to pass high-pressure fluid lines cleanly through metallic enclosures, panels, or structural bulkheads. This configuration features an extended parallel thread body and a robust heavy-duty locknut to keep your plumbing rigid and vibration-isolated.
3. Elbow BSPT Adapters
Ideal for routing layouts around sharp corners or transitioning fluid ports, our BSPP to BSPT Elbows feature a 90-degree forged body. They bridge parallel British threads (BSPP) with British Standard Pipe Tapered (BSPT) configurations seamlessly, utilizing mechanical thread deformation for a leak-free structural anchor.
4. G Thread with ED Seal (G-ED Seal)
Engineered for high-pressure port connections in hydraulic manifolds, pumps, and control valves. The parallel G thread utilizes a specialized captive Profile Elastic Seal (ED-seal). This elastomer expands under torque to completely shut off leakage paths without requiring unneeded thread tape or paste sealant.
5. Tee Unions
Our three-way BSPP Tee Unions facilitate system fluid splitting or pressure drop lines across a unified 60° cone interface block. The forged cross-sections handle heavy structural loads and fluid shocks efficiently.
