{"product_id":"5-16-pipe-imperial-unf-bsp-bsf-unions","title":"5\/16 Pipe - Imperial (UNF\/BSP\/BSF) Unions","description":"\u003cp\u003eWhen you're working on classic British vehicles, American imports, or any system still running imperial brake and clutch lines, having the correct unions is non-negotiable. These essential fittings provide the secure, leak-free connections vital for hydraulic integrity.\u003c\/p\u003e\n\n\u003cp\u003eFrom repairing a localised corroded section to fabricating an entire custom hydraulic line, these imperial unions are designed for reliability. They are critical for technicians undertaking restorations, bespoke builds, or routine maintenance where original components are no longer viable or available. A precise, well-seated union is the foundation of a safe, functional braking or clutch system.\u003c\/p\u003e\n\n\u003ch3\u003eMaterial Considerations: Copper vs. Copper-Nickel\u003c\/h3\u003e\n\n\u003cp\u003eChoosing the right pipe material is as important as the union itself, and each has its place in the workshop:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCopper:\u003c\/strong\u003e A traditional choice, copper pipe is highly valued for its malleability. It's exceptionally easy to form, bend, and flare, making installation straightforward, particularly in complex routing or tight spaces. For many standard repairs and custom lines, copper provides an excellent balance of workability and performance.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCopper-Nickel (CuNi \/ Kunifer \/ Cupro-Nickel \/ NiCopp):\u003c\/strong\u003e For applications demanding maximum durability and resistance to harsh environments, copper-nickel is the superior option. While slightly stiffer to work with than pure copper, its significantly higher resistance to corrosion means it stands up far better to road salt, moisture, and general workshop contaminants. Furthermore, its increased fatigue strength provides an extra layer of resilience, making it a preferred choice for long-term reliability in demanding conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eRegardless of your pipe material choice, these unions are manufactured to exacting standards right here in the UK. This commitment to quality ensures a consistent fit and reliable performance, providing peace of mind that your hydraulic connections are sound.\u003c\/p\u003e\u003cp\u003eImperial unions for brake and clutch pipes. All made to the highest quality in the UK.\u003c\/p\u003e\u003cp\u003eCooper pipes are more traditional and easier to work with however Copper Nickel (aka CuNI, Kunifer, cupro-nickel or NiCopp) is more resistant to corrosion and has a higher fatigue strength.\u003c\/p\u003e\u003cp\u003e\u003csvg width=\"100%\" height=\"100%\" viewbox=\"0 0 1861 302\" version=\"1.1\"
