Buy & Import Extension Nipple from Sterling Overseas - Wholesale Supply

Extension nipples from Sterling Overseas are threaded pipe fittings with male threads on both ends, designed to extend or connect pipeline segments in industrial and plumbing systems. They are manufactured in brass CW614N or stainless steel 304, with standard thread sizes ranging from 1/8 inch to 2 inches NPT. Each fitting is precision machined to meet dimensional tolerances of ±0.05 mm and complies with ASME B1.20.1 for thread geometry.

Brass versions offer good corrosion resistance in water and low-pressure gas systems, while stainless steel 304 variants suit aggressive environments such as chemical processing or marine applications. The material choice affects both durability and thermal expansion performance. These fittings are typically produced using cold heading and CNC threading, with surface finishes ranging from natural brass to polished or passivated stainless steel. Standard lengths vary from 15 mm to 150 mm, depending on thread size and application.

These extension nipples are commonly purchased by distributors in plumbing, HVAC, oil and gas, and water treatment sectors across Southeast Asia, the Middle East, and Africa. Buyers typically order in bulk quantities of 500 to 5,000 pieces per shipment, packed in polybags inside cartons with unit identification labels. Trade terms are usually FOB Mumbai or CIF destination, with lead times of 15 to 25 days after order confirmation. Packaging can be customized for containerized bulk or retail-ready units upon request.

Frequently Asked Questions About Extension Nipple from Sterling Overseas
Thread pitch follows ASME B1.20.1 standards with a tolerance of ±0.02 mm per thread. This ensures compatibility with standard female fittings. Buyers should request a thread gauge report if using in high-pressure or critical sealing applications.

Sourcing Extension Nipple from Sterling Overseas - India Import Guide

Before placing an order, verify the material grade certification for brass CW614N or stainless steel 304 with a material test report (MTR). Confirm thread dimensions using a thread gauge, especially for sizes above 1 inch, as non-standard threading can cause installation failures. Request a sample batch to inspect surface finish and internal bore consistency, particularly if used in pressurized systems.

Lead time is typically 15 to 25 days after order confirmation, depending on material availability and production scheduling. Incoterms are usually FOB Mumbai, but CIF or CFR may be available upon request. Payment terms are commonly 30% advance with balance against shipping documents. Confirm whether the supplier handles export documentation such as Certificate of Origin and Commercial Invoice, as these vary by destination country.

For quality assurance, request batch-level inspection reports covering dimensional checks, thread accuracy, and visual defect rates. For stainless steel, ask for a passivation test report to confirm corrosion resistance. Ensure packaging includes protective caps on threads and moisture-resistant wrapping. Retain samples from each shipment for traceability in case of field failures.
