CTS Stainless Steel Insert Stiffeners

CTS Stainless Steel Insert Stiffeners, made from durable 304 stainless steel, are designed to reinforce CTS SDR-9 polyethylene or high-density polyethylene tubing (sizes 3/4" to 1") during the use of brass compression fittings. These inserts prevent tube collapse by fitting inside the tubing and feature dimples and flanges to ensure secure placement within the service line.

LF Brass Compression x Male Pipe Thread Adapter Copper Tube Size

The LF Brass Compression x Male Pipe Thread Adapter Copper Tube Size ensures secure, leak-free connections between CTS copper or HDPE piping and female-threaded plumbing systems. Made from lead-free brass and rated for 300 PSI, it meets AWWA C800 and NSF/ANSI 61 & 372 standards, making it ideal for residential, municipal, and irrigation use. Designed for 3/4" and 1" CTS service lines, the adapter provides a reliable Compression x Male Pipe Thread connection. When used with HDPE, insert stiffeners are required. Note: CTS fittings match the pipe outside diameter and are not interchangeable with IPS fittings.

Copper Tube Size LF Brass Compression Coupling Without Stop

Copper Tube Size LF Brass Compression Coupling Without Stop are designed for use with copper tube and High-Density Polyethylene (HDPE) pipes, allowing the pipe to pass through the coupling body. Commonly used for service lines ranging from 3/4" to 2", these couplings require marking the pipes for proper alignment and use of insert stiffeners with flexible plastic pipes. Installation involves sliding the coupling over both pipe ends, aligning with marks, and tightening the H nut to compress the gasket and gripper for a watertight, pull-out-resistant seal. For copper tubing, an electrical conductor spring ensures conductivity, though it serves no function with HDPE.

FAQs

1. What makes the Cambridge Brass Compression x Male Pipe Thread Adapter ideal for water service lines?

This adapter features lead-free brass construction and a pressure rating of 300 PSI, making it safe and strong for potable water applications. It connects CTS copper or HDPE tubing to threaded plumbing systems while meeting AWWA C800 and NSF/ANSI 61 & 372 standards for compliance and performance.

2. How does the coupling without a stop from Cambridge Brass ensure proper alignment during installation?

The Copper Tube Size LF Brass Compression Coupling Without Stop allows the pipe to pass completely through, requiring installers to mark pipe insertion points for accurate alignment. This design ensures the gasket and gripper compress correctly, forming a tight, secure seal when the H nut is tightened.

3. What are the key installation tips for Cambridge Brass compression couplings on HDPE lines?

When using Cambridge Brass compression couplings on HDPE pipes, always insert a stainless steel stiffener to support the pipe internally, mark the pipe for alignment, and ensure even gasket compression by tightening the H nut fully to achieve a leak-free, pull-out-resistant joint.

4. Are Cambridge Brass fittings interchangeable with IPS-sized piping systems?

No, Cambridge Brass compression fittings are sized for CTS (Copper Tube Size) and match the pipe’s outside diameter. They are not interchangeable with IPS (Iron Pipe Size) fittings, which have different dimensions and could lead to installation issues or leaks if mismatched.

5. Why is lead-free brass important in Cambridge Brass water fittings?

Lead-free brass ensures that Cambridge Brass fittings meet NSF/ANSI 61 & 372 standards for safe potable water contact. This protects public health by eliminating the risk of lead contamination in drinking water, a critical factor for compliance with modern water safety regulations.
