FAQ
What is the difference between BSPP and NPT threads in hydraulic gauge fittings?
BSPP (British Standard Pipe Parallel) threads are straight and require a bonded seal washer or O-ring to create a seal. NPT (National Pipe Tapered) threads are tapered and seal through thread interference, often using thread sealant. It is crucial not to intermix these threads as it will cause leakage and damage.
When should I use a fitting with a pulsation damper?
Use a pulsation-dampening or snubber fitting whenever your hydraulic system experiences rapid pressure cycles, shocks, or vibrations (common in pumps, cylinders, and valves). This protects the internal mechanism of the pressure gauge, ensuring accurate readings and preventing premature needle flutter or gauge failure.
Can I use brass fittings for all hydraulic fluids?
While brass offers excellent corrosion resistance, it is not suitable for certain phosphate ester-based fire-resistant fluids (e.g., Skydrol). For such media or in high-pressure applications above typical brass ratings, we recommend our carbon steel or stainless steel hydraulic gauge fittings. Always confirm material compatibility with your system fluid.
Do you offer kits for multiple gauge installations?
Yes. We provide pre-assembled gauge manifolds and block fittings that allow you to mount multiple gauges, switches, or transducers from a single port. This simplifies plumbing, reduces potential leak points, and creates a cleaner, more organized system layout.
What certifications do your products hold?
Our manufacturing process and quality systems are certified to ISO 9001. Specific products can be supplied with material certifications (e.g., 3.1 Mill Certificate per EN 10204) upon request to meet the documentation requirements of critical industries.
