What is upvc Socket 3″ GM Local ?

 

The “GM Pressure” brand for a UPVC Socket 3″ Schedule 40 (Sch 40) pressure fitting appears to be a local or regional brand, as specific, widely-recognized industry details for a brand with that exact name were not found in a general search. However, I can provide a comprehensive detail and specification breakdown based on the universal standards for UPVC (or PVC) Socket 3″ Sch 40 Pressure Fittings, along with installation and usage instructions.

This information applies to any manufacturer, including a local brand like “GM Pressure,” as they must adhere to these industry standards to produce a viable product.

 

I. General Specifications & Description

 

The fitting you are asking about is a 3-inch PVC/UPVC coupling designed for use in pressure piping systems.

 

A. Key Term Breakdown

 

  • UPVC (or PVC): Un plasticized Polyvinyl Chloride. A durable, rigid plastic material widely used for piping due to its corrosion resistance, light weight, and low cost.
  • Socket (Slip): Refers to the end connection type. A socket or “slip” end is an unthreaded opening designed to receive the end of a pipe. The joint is made permanent by a process called solvent cementing (or solvent welding).
  • 3″: The Nominal Pipe Size (NPS). This fitting is designed to join two lengths of 3-inch PVC Schedule 40 pipe.
  • Sch 40 (Schedule 40): Refers to the wall thickness of the pipe and fitting. Schedule 40 is a common standard wall thickness for pressure applications.
  • Pressure: Indicates the fitting is designed to handle internal pressure, differentiating it from thinner-walled Drain, Waste, and Vent (DWV) fittings.
  • GM Pressure: The presumed local brand name.

 

Feature Detail
Material Un plasticized Polyvinyl Chloride (UPVC or PVC).
Standard Typically conforms to ASTM D2466 (Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 40).
PVC Cell Class Usually meets ASTM D1784 Cell Classification 12454 (Type I, Grade 1 PVC).
Potable Water Often certified by NSF International for use with potable (drinking) water.
Color Schedule 40 pressure fittings are typically White.
Max. Service Temp. (). PVC becomes softer and its pressure rating is significantly reduced at higher temperatures.
3″ Pipe O.D. The outside diameter of the matching 3″ pipe is inches.
Pressure Rating Varies by manufacturer and standards, but a 3″ Schedule 40 pipe typically has a Maximum Working Pressure (MWP) of about 260 PSI at . The pressure rating of the fitting is often considered equal to or slightly less than the pipe it’s designed to connect.

Installation Steps

  1. Cut the Pipe: Cut the end of the PVC pipe perfectly square (perpendicular to the pipe axis).
  2. Deburr and Chamfer:
    • Deburr the inside edge of the pipe to remove any plastic shavings.
    • Chamfer (Bevel) the outside edge of the pipe to a slight angle (about to ) to help it enter the fitting and prevent the pipe from scraping the cement out of the socket.
  3. Dry Fit and Mark:
    • Insert the pipe into the fitting socket until it bottoms out. The pipe should fit snugly, going about to of the way in before becoming tight.
    • Mark the pipe at the mouth of the fitting to ensure full insertion during the final, cemented assembly.
  4. Clean and Prime:
    • Wipe the pipe end and the inside of the fitting socket with a clean, dry rag to remove all dirt and moisture.
    • Aggressively apply PVC Primer (often purple-tinted) to both the inside of the fitting socket and the outside end of the pipe (up to the mark). The primer softens and prepares the plastic for the cement. Keep both surfaces wet.
  5. Cement:
    • While the primer is still wet, apply a heavy, even coat of PVC Solvent Cement to the outside of the pipe end.
    • Immediately apply a medium coat of cement to the inside of the fitting socket.
  6. Assemble:
    • Immediately and without hesitation, insert the pipe fully into the fitting socket until it hits the stop.
    • Give the pipe a -turn (90-degree twist) while inserting to help distribute the cement evenly and ensure a complete bond.
    • Hold the joint for to seconds to prevent the pipe from pushing itself out of the socket (push-out).
