FAQ
- Q: What thread standard do you use for your marine thru-hull fittings?
- A: Our standard molds are optimized for standard marine straight threads like NPSM (National Pipe Straight Mechanical) and BSPP (British Standard Pipe Parallel). However, as a dedicated OEM foundry, we can completely customize the thread pitch, length, and diameter according to your specific engineering prints.
- Q: Does this bulkhead fitting come complete with the hex locking nut and washer?
- A: Yes. We supply the complete integrated OEM kit including the investment cast thru-hull body, matching heavy hex nut, and a flat stainless steel or friction washer to provide your buyers a retail-ready solution.
- Q: Can you guarantee this component is safe for sub-waterline (below the waterline) installation?
- A: Absolutely. Below-waterline parts demand zero compromises on quality. Our silica sol investment casting process produces incredibly dense, non-porous metallic grain structures that deliver elite structural strength and pressure tightness. Combined with 100% spectrometer material verification, our fittings are fully trusted by international boat builders for critical marine safety applications.
