Change Notice: Changed to New MPAPS format; Combined GS, PP, NPP. 1.0 GENERAL: This standard conforms to SAE Standard J531 and covers specifications and dimensions for those types of pipe, filler an
5、d drain plugs having tapered pipe threads which are commonly used in automotive and related industrial applications. 2.0 CONTENTS: 3.0 MISCELLANEOUS DIMENSIONS AND TOLERANCES: The tabulated dimensions will apply to the finished parts, plated, hardened or otherwise processed or specified by the purch
6、aser. Maximum taper on head of square head plugs will be minus four degrees total. Tolerance on dimensions not otherwise limited will be plus and minus .010 inch. The minimum across corners dimensions of external hexagons will be 1.092 times the nominal width across flats. The minimum across corners
7、 dimensions of external squares will be 1.25 times the nominal width across flats, but will not result in a side flat width of less than .75 times the nominal width across flats. At maximum material condition, the radii at corners of hexagon and square sockets in broached and upset plugs will not ex
8、ceed .005 inch. 4.0 THREADS: The pipe threads on Automotive Pipe Plugs, unless there is specific authorization to the contrary, will conform with the Dryseal American Standard Taper Pipe Thread (NPTF) and be gaged accordingly.

12、nsus of manufacturers and users that trouble-free assembly and pressure-tight joints without lubricant or sealer cannot be assured unless a full length of thread is used. The pipe threads on Automotive Filler and Drain Plugs, unless there is specific authorization to the contrary, will conform with
13、the Dryseal SAE Short Taper Pipe Thread (PTF-SAE Short) and be gaged accordingly. The Automotive Filler and Drain Plug dimensions are based on the length of the (PTF-SAE Short) thread and are primarily intended for assembly with Dryseal American Standard Taper (NPTF) or Dryseal American Standard Int
14、ermediate Straight (NPSI) internal pipe threads in installation where it is desirable to limit the entry of the small end of the plug. Limitation on other applications of this thread are explained in the SAE Dryseal Pipe Thread Standard. Pipe threads will be chamfered or rounded to the closest 1/64
15、inch diameter smaller than the minor diameter within a tolerance of minus .016 inch to produce approximately one incomplete thread and not to exceed one and one-half incomplete threads. The pipe threads on square and hexagon socket plugs will be full or complete for the overall length specified and
16、will be chamfered on both ends. Specifications for Dryseal pipe threads and related specifications covering blank sizes, dies or chasers, gages, gaging, etc., are given in detail in the SAE Dryseal Pipe Thread Standards. Sealant Coating: All fittings that have external pipe threads will be furnished
17、 with a pre-applied sealant coating on the pipe threads that meets the requirements of CEMS D-31. 5.0 POLICY FOR SELECTING PARTS FOR NEW DESIGN: Approved parts are so designated to reduce variety of parts and assure maximum availability, interchangeability, and cost savings in volume buying. For new
18、 design, parts shall be selected from “Approved“ part list only. Material: Brass (BRS) Finish: Plain (PLN) Design: Hex 6.0 MATERIAL: Plugs may be made by casting, forging, milling from the bar or upsetting from a grade of material free from defects that might affect their serviceability.
