Common Concerns Answered
Is NPS thread compatible with NPT?
No, NPS (National Pipe Straight) threads are designed for straight connections and do not self-seal like NPT (National Pipe Taper) threads. Ensure you use a compatible NPS fitting or adapter if a transition is necessary. The specific design of this GROCO fitting utilizes NPS for its intended application.
Why is this bronze fitting more expensive than plastic alternatives?
The higher cost reflects the superior durability, corrosion resistance, and longevity of C83600 bronze compared to plastic or lower-grade metals, especially in harsh marine environments. This investment prevents costly premature failures and repairs.
How do I ensure a watertight seal with this thru-hull?
Proper installation is critical. This involves ensuring the hull surface is clean and properly prepped, using marine-grade sealant (like 3M 5200 or equivalent) on the hull-side of the flange, and tightening the fitting securely without over-stressing the hull material.
